Bios Mods -The Best BIOS Update and Modification Source

Hello,

I have the Asus rog desktop prebuilt G35CG that has the motherboard Z590-F, but Asus locked the bios for that motherboard and the model name appear as G35CG.
The bios has very limited options, and no q-fan or XMP control.
I’m trying to understand how I can update/unlock the bios of the Z590-F for my build.

G35CG Bios:

Z590-F Bios:

Thanks in advance…
