Sure!
[EDIT] added the EFI with OpenCore 0.7.7
This EFI is based on OpenCore 0.7.6 and 0.7.7 and MacPo7,1 system definition, Apple WiFi card in the WiFi card slot on the board and a 6800 XT.
At this time it runs Monterey 12.2.
But i have to warn that macOS updates tend to be a bit funky since Monterey (with my EFI?).
At times it seems as if the computer is stuck at some boot-stage. If in doubt if it continues after some minutes, just switch it off and on the hard way with the power button. Usually it then boots just fine.
Notes:
- Platforminfo is anonymised and has to be filled with your own values
- HideAuxiliary is enabled, so not all partitions show up
- simple Bootpicker with indefinite timeout
- the SMC kexts for temps and stuff aren't activated
- custom USB mapping kext adjusted for MacPro7,1 system definition
- RestrictEvents.kext added to eleminate the RAM-warning on MacPro7,1 system definition
- CpuTscSync.kext is used instead of TSCAdjustReset.kext
- the Smalltree driver is not working anymore, so only one LAN port
