EDIT 1: December, 28, 2020 - Updated to Big Sur 11.1 and fixed USB 3.1 ASMedia USB 3.1 controller issues. More info on post 12. Updated kexts, full EFI uploaded - EFI_2020.12.28_BigSur_11.1
EDIT 2: January, 09, 2021 - Updated to OC 0.6.5 and all the kexts. My motherboard BIOS does NOT have an option to enable/disable the CFG Lock. So I managed to find the offset and I switched it off using this thread. The offset is 0x502 with value 0x00 - off or 0x01 - on (BIOS v. F10b). The Quirks AppleCpuPmCfgLock and AppleXcpmCfgLock are now changed to NO. If you are not sure how to change this, please set them back to YES. Full EFI uploaded - EFI_2021.01.09
EDIT 3: July, 10, 2021 - Updated to macOS Big Sur 11.4, OC 0.7.1 and all the kexts. Full EFI uploaded - EFI_2021.07.10
Currently upgraded from Catalina 10.15.7 to Big Sur 11.0.1.
