Bios Mods -The Best BIOS Update and Modification Source

Hi all!
I need to modify my own BIOS file to unlock hidden features on it, but it's locked by the manufacturer so I not be able to see any modification section on AMIBCP of other kind of modding tool, evein if I can extract/add modules, and also microcodes updates.

Is there a way to manage what I ask for?


Thanks!
