Modifying VBIOS/MXM GPU Hardmod

Is there a way to modify a VBIOS of a laptop graphics card or do a hardmod to unlock the TDP for better performance, particularly for a Clevo one? If so, how do you do it? If we can modify the BIOS to unlock performance for the CPU with the Prema BIOS, I figure we can do it for the GPU as well.

Depends on what Gpu are we talking about.

If its a Pascal card or some Turing (with limited support) you can try with Mobile Pascal TDP Tweaker. (you can flash moded bios only with a programmer afterwards).

A hard mod will be a shunt mod but I have no experience with those nor I do recommend it (you could fry the card really fast if not extra careful as there is no firmware safety net).

 

PS I do not recommend raising TDP to any GPU in that matter as you can cut its rated life expectancy really fast.
