Well, if the card is in a format normally supported by Big Sur, sorry, this beats me. Maybe something else in your config that I missed. There were a lot of ACPI patches and you also force injected kexts for some reasons. Good luck.

Proceed with caution; preferably on a separate disk or partition. Use OC off a USB key rather than overwrite your existing Clover EFI partition. But that's a matter for a separate thread.

No need to take out kexts, you can disable/block them by pressing the spacebar at the Clover GUI.

I think you may need Clover r510x minimum to boot later versions of Catalina. Certainly never used anything lower than Clover r505x with any of my Catalina installations. @nickelnoff, you should be able to replace the Clover boot files (bootx64, cloverx64) and .efi drivers from any computer/OS (even Windows) on your USB key. The hidden EFI partition is normally FAT32... Here are files for r5107 for instance (boots 10.15.7 without issues): r5107.zip

v4910 might not be able to boot catalina 10.15.7 Replace your USB Clover files with my generic Clover file v5119. Just keep your kexts/ACPI folder and Config.plist
