[REQUEST] Sony VAIO SVE151 & SVE171 Series (R01x0D6) - BIOS Unlock

[Dudu2002]

Hello

I want to unlock the bios of my Sony Vaio SVE17127CXB

BIOS VERSION: R0140D6
ME VERSION 8.1.0.1248

It has an i7 3740QM with a Radeon 7650M

I want it to be able to switch between the disabled Intel HD Graphics 4000 and the Radeon
And disable the Radeon

I am new to this, how can I extract the current bios and flash the unlocked one?

Thank you!
