I was able to extract the PowerPlay tables from the Frontier Edition vbios and apply them in software on the WX9100 flashed card. It seems to work on both the current PRO (22.Q4) and Adrenaline (22.11.2) drivers.
Download the file below and change the extension from .txt to .reg. Double-click to apply to your registry. You’ll need to reboot to reload the driver.

Note that if you have other display adapters attached (e.g., virtual display, BMC GPU, second GPU, etc.) you may need to first change the display enumerator in the registry key from “\0000” to your WX9100’s.
EDIT: Attached table as a file now that I am no longer a “new user”.
