RehabMan SSDT trick used to disable unsupported Nvidia and keep it in pcie slot while using Mojave
For people like me who want to keep their unsupported videocard in pcie slot 1 (or 2, or 3, I suppose) while testing Mojave with a second supported videocard in another pcie slot (or integrated igpu), take a look at @RehabMan Guide : [FIX] "Window Server Service only ran for 0 seconds" with dual-GPU
Thanks to his SSDT method, I've managed to disable my watercooled 1080ti which is now undetected by Mojave, only my cheap R9 270 working OOB is listed in "System report".
Sleep/Wake is now working perfectly, before that I had reboot on wake because of the 1080ti lack of drivers, or black screens when trying both cards at the same time.
A short description of the problem before this great trick can be found here, but really, it's very easy to do, thanks to RehabMan precise guide.
Here's my graphics/Displays system report, while having the 1080ti powered and inserted in pcie slot 1, fully functional under Windows 10 or Sierra in multi boot.

这个如果能实现的话，太有意义了，
mac pro开机的时候随便用一张亮机卡，比如最便宜的GT120 730mac之类
进入系统后 ，屏蔽这个插槽，用其他的插槽的显卡，这样显卡就不用拔掉了

?? 如何屏蔽 ?

挖个坟，有实现方法了吗？我得情况差不多，也是两张显卡，一张1060，一张免驱K600，单独插K600已经完美使用了，插双卡就只能不带驱动启动了。卡死了。
