Building my first egpu, noob question...

Flame me if you will. Was a console gamer until very recently. Building my first egpu with the aoostar ag02. Will be using this with my Onexplayer f1 pro and rog flow. Is it possible to flash a vbios for the card I'm using without messing up the igpu? Can't find much info online. Is it much riskier compared to a normal vbios flash? Thanks in advance.
