Unlocking onboard Intel UHD Graphics G1

I understand that the UHD Graphics G1 is based on the Ice Lake GT1 graphics processor, but unlike the fully unlocked Iris Plus Graphics G4, which uses the same GPU but , does not have all 384 shaders enabled. Instead it features 256 shading units.

I’m interested in finding out if the UHD is capable of being unlocked, specifically on my ASUS X515JAB.309 laptop?

Please can anyone point me in the direction of any existing guides, or to help me to understand how to mod this GPU to unlock the unused shader units.
