Apple released 10.14.1 DP1 and 139.0.0.0.0 Mac Pro BootROM.
No boot screens for UEFI cards,
no NVMe EFI module added,
no FileVault2,
same microcodes,
still safe to insert the NVMe EFI module.
Code:$IBIOSI$ MP51.88Z.F000.B00.1808171030Apple ROM Version Model: MP51 EFI Version: 139.0.0.0.0 Date: Fri Aug 17 10:24:21 2018 Build Type: ReleaseFirst post about 139.0.0.0.0 #1242
20180813: 138.0.0.0.0
New BootROM 138.0.0.0.0 for Mac Pro 5,1 with updated microcodes (0x106A5 29 and 0x206C2 31), support for 5GT/s link speed on macOS/Windows without R17 mod, enabled HDMI audio on RX480 and new/improved firmware flasher on Mojave DP7/PB6 (18A365a) full installer.
Now seems you don't need a Mac EFI GPU to flash it, but the Mojave installer checks for a Metal supported one before upgrading the BootROM. @Squuiid confirmed flashing with a RX580, sadly without boot screens/boot selector.
Attention:
The new Firmware Flasher don't have the usual progress bar, just a grey screen on Mac EFI GPUs, or a black one with a PC GPU, and the usual DVD tray opening. Since the new flashing process don't have progress indicator/completion and seems to take longer to complete and shutdown the Mac Pro, you have to wait until the shutdown/restart.
Updated microcodes:
5GT/s link speed in a HD 7870 without R17 mod:
BIOS version:
The complete BIOS version for 138.0.0.0.0 is MP51.88Z.F000.B00.1807300628
NVMe support:
Apple did not add the NVMe EFI module with 138.0.0.0.0, but the injection method is the same as was done with High Sierra - no changes.
What I have to do to upgrade the firmware:
If your Mac Pro have a BootROM earlier than MP51.0089.B00, to upgrade to 138.0.0.0.0 you will have to do:
Download the full Mac App Store installer for 10.13.6, open it and then do as the installer says to upgrade to MP51.0089.B00. After the firmware upgrade reboot, you can close the installer app.
Download the full Mac App Store installer for Mojave, the most recent one, open it and then do as the installer says to upgrade to 138.0.0.0.0. After the firmware upgrade reboot, you can close the installer app.

Install macOS 10.14 Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012)
Learn how to prepare your Mac Pro (Mid 2010) or Mac Pro (Mid 2012) for macOS Mojave.
macOS Mojave requires a graphics card that supports Metal, an Apple technology that lets the system and apps efficiently tap into the capabilities of today’s graphics processors (GPUs). The graphics cards offered by Apple in Mac Pro (Mid 2010) and Mac Pro (Mid 2012) don't have GPUs that support Metal, so these systems require upgraded graphics cards in order to install macOS Mojave.
Before you upgrade to macOS Mojave on these Mac Pro models, you need to update to macOS High Sierra 10.13.6 and then make sure that your graphics card is compatible. You also need to turn off FileVault.
Update to macOS High Sierra 10.13.6
First, use the Mac App Store to update your operating system to macOS High Sierra 10.13.6. Don't upgrade your Mac Pro (Mid 2010) or Mac Pro (Mid 2012) to macOS Mojave directly from macOS versions prior to 10.13.6.
Make sure that your graphics card works with Mojave
Next, check to see if the graphics card in your Mac Pro is compatible. You can use System Information to find out which graphics card your Mac has:
1.Press and hold the Option key while choosing Apple () menu > System Information.
2.In the sidebar, select Graphics/Displays. If your graphics card is compatible, you see "Supported" next to the Metal entry. You can also note the name of your graphics card and see if it's in the list below.
These specific third-party graphics cards are Metal-capable and compatible with macOS Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012):
•MSI Gaming Radeon RX 560 128-bit 4GB GDRR5
•SAPPHIRE Radeon PULSE RX 580 8GB GDDR5
•SAPPHIRE Radeon HD 7950 Mac Edition
•NVIDIA Quadro K5000 for Mac
•NVIDIA GeForce GTX 680 Mac Edition
Some other third-party graphics cards* based on the following AMD GPU families might also be compatible with macOS Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012):
•AMD Radeon RX 560
•AMD Radeon RX 570
•AMD Radeon RX 580
•AMD Radeon Pro WX 7100
•AMD Radeon RX Vega 56
•AMD Radeon RX Vega 64
•AMD Radeon Pro WX 9100
•AMD Radeon Frontier Edition
If the graphics card in your Mac Pro isn't listed above, you need to install one that's compatible with macOS Mojave. If you need additional help, contact Apple Support.
* Third-party graphics cards vary, so you should check with the vendor of your specific graphics card for compatibility details.
Turn off File Vault, then install macOS Mojave
Many third-party graphics cards won't show anything on the display when macOS Mojave is starting up, including the Apple logo and startup progress bar. As a result, you can't log in to a system that uses FileVault, choose a different startup disk before your Mac boots into macOS, or perform some hardware diagnostics.
You’ll need to turn off File Vault and then follow the steps to download and install macOS Mojave on your Mac Pro.

If your Mac has more than one volume with macOS installed, you need to use the Startup Disk pane in System Preferences to switch between operating systems. Holding down Option while restarting doesn't allow you to choose an operating system on these Mac Pro models.
