For my FTW3 3080 Hybrid gpu-z reports that I'm using 94.02.42.C0.04 BIOS, I see that only 105% is allowed. I'm guessing I'd have to update to 94.02.42.80.FC to get to the 450W bios?
Edit* Found the Jacob thread with the .exe files to update to 94.02.42.80.FC and can get over the 105% cap from before.
