The PCI ID is 1002 73bf which is listed in the kext.

Maybe I should try using DeviceProperties to force load one of the new framebuffers?

I think it all comes down to the AMDRadeonX6000.kext missing Navi21 references, framebuffer on its own will not be sufficient.

I've been trying to edit info.plist files in all AMDRadeonX6000xxx kexts to add Navi21 and Device-ID code. Still no luck

We will. We're just waiting/hoping for a Big Sur 11.1 beta to add acceleration. So there won't be any news until 11.1 beta 3 arrives, at the earliest.

13 days passed between 11.1 beta 1 and beta 2, so if they keep to a similar two-week schedule, beta 3 might arrive around December 17th. Of course no guarantees it will have full support..
