PS31: 
I got this running on my 9020 SFF.
Major issue I had here was not working SATA that's used for ODD. To avoid rebooting million times, I enabled every non-IME device in the devicetree, changed SATA map to 0x3f and rebuilt - after a reflash, all SATA ports were working correctly.

I'll try to tinker more tomorrow with GOP in EDK2 as I'm using an RX 6400 which makes libgfxinit a bit useless in my daily usage 😊

Also, would it be possible to enable ReBAR? I've tried enabling it and changing BAR size from 37 and below. Not sure if this idea was straight up insane and unrealistic but well - it didn't work.
