[REQUEST]Sony Vaio EB2S1E Advanced BIOS

Hello!
I have a Sony Vaio VPC-EB2S1E notebook and I really want to have acces to all those hidden settings.

Can you guys help me unlock them? I tried by myself but I'm not doing so good. And I'm afaid to flash my "unlocked" bios rom and brick my laptop..

PS: Is there a way to unlock the iGPU? Although my procesor is a 1st gen i3, it has an integrated GPU, but blocked by Sony.

Noticed these lines in AMIBCP:
iGPU Digital Port B - Mode Muxed with dGPU
iGPU Digital Port C - Mode Muxed with dGPU
iGPU Digital Port D - Mode Muxed with dGPU

I've attached the dumped rom + rom from official site.
