This old Award 6 bios generation… not easily done… even if possible and if such string/variable exist in bios, try https://www.bios-mods.com/
EDIT: No specific tool or of easy use, if its possible to do it it will be hex edited, there were tools for this like the Award modbin6 tool but it was for earlier/small Award 6 bioses, trie it if you want, im not gonna loose time with this and ask here for any tools, search yourself.
