Thanks for the quick reply! I will add the DSDT file and modify my config.plist to match yours as closely as possible.
However, with me having the RX5700, I need to have the adgpmod=pikera and -disablegfxfirmware boot flags enabled. Otherwise, the 5700 does not display and it gives a halt. Can you foresee this being an issue with the DSDT file that you have supplied?
I have also read that since Catalina supports the 5700 natively, would you recommend that I remove Lilu and Whatevergreen? Or leave them alone?

one other question... Asus and ASRock motherboards require the AptioMemoryFix driver, correct? (my system will not boot without it)
What about the using the EmuVariableUefi? I had read that it helps with some shutdown problems on certain boards. Can you see any harm in using it?
