Dell Vostro 3450 Advanced Options unlocking in progress

[HairyCube]

I unpacked the BIOS file with PhoenixTool and found the following strings in "CFEF94C4-4167-466A-8893-8779459DFA86_1_1071.ROM":
S w i t c h a b l e G r a p h i c s
S w i t c h a b l e G r a p h i c s M o d e
S w i t c h a b l e G r a p h i c s M o d e s e l e c t .
M u x e d
M u x l e s s
d G P U
This is exactly what I'd really like to see unlocked
Also, this file has lots of other interesting strings. You can disable Intel Management Engine, for example (which I'd also love to do since it's annoying).
I wonder if anyone can help me with unlocking all these options as I'm not a BIOS hacker

EDIT:
Also found the following strings, which would be an even better choice:
Primary Display Device
IGD
PEG
PCI
