got Big Sur to run with my RX 6800 XT + 9900K with your latest EFI folder using the agdmod=pikera boot argument.
Thank you so muhh! Got 2 issues now to tackle:
1) USB issue. I tried replace the SSDT files with the custom SSDT I made and that seems to work although still had weird things happen at the end but was usable. Mac os won't boot with the files below in the ACPI >patched/origin folders. Your work but I can't read an SD card with my installation then for some weird reason but large external HHD and SSDs work.
@pastrychef , if you got a minute, do you see anything wrong or something I'm missing or overlooked in the two SSDT files I had (attached). The one named SSDT-LPC was in Origin. I did a while back after days of trying to figure it out SSDT.
2) when clover boots, I can only boot via Preboot and there is no regular non-preboot option like usual. Should I be concerned? any guess why would it do that?
Sorry if this is a bit long! any insights into these would be amazing! thanks!
I can't even open the SSDT-UIAC. It might be corrupt.

With newer versions of macOS booting from Preboot is normal.
