[REQUEST] Acer Aspire E1-572 BIOS Unlock

Hi, I need some help to install the modded bios for this laptop, to disable the integrated graphics card. I know how to disable integrated graphic card but it seems there is no advanced menu.

Thanks in advance...

EDIT: I found some links but they're all dead.
