[REQUEST] Sony Vaio SVF15N1S2ES Fit Multy-Flip

[Z3PHYR]

Hello,

-Bios Version: R1140DD
-Bios Type : Insyde EFI
-CPU I5 4200U

I want to add nvme support to this laptop, and also modify the nvidia egpu vbios to increase maximum tdp, and increase the maximum OC limit to the same as nvidia 740m (the laptop uses 735m which is supposed to be the same chip).
Also if there are any other hidden settings that might be usefull to increase the performance that would be fantastic .
I also want to learn how to do this, I tried to learn myself but I cant seem to find enough information to get going, I managed to extract my bios using CH341A chip programmer, because I could not find a way to make a dump of the bios, sony uses some strange compressed exe that flashes the bios but the contexts are weird (I will also attach that, I had to extract the exe and then zip it to a .zip because I cant upload exe files here).

Any help is appreciated, if nothing else I hope someone can point me in the right direction how to learn this
