Acer E1-421-0-BR899 UEFI 2.12 Unlock

Hello there

Any one here could unlock this BIOS to get access to Advanced menu settings ?

If UEFI is impossible to unlock is there a way to flash a non-UEFI BIOS over ?

I do not even the Windows 8 SL that came here since I upgraded my HD and had 1 spare W8 pro licence...

BTW, other BIOS for the 421 could be used here ? The differece is about keyboard layout (here is brazilian ABNT) and I remeber a day with my old notebook (Mirax) that I used a BIOS for diff language and it scrowed some keys...

Tks
