Msi GTX 560TI OC BIOS moding uefi

Hello guys i need some help. My msi 560 ti dont have UEFI GOP anyone can help me to modify a rom to use UEFI?

The BIOS chip on GTX560/570/580 is too small to accommodate a modified BIOS with GOP so even if you mod it it won’t physically fit onto the chip.

But i read somewere thats can be possible! Can someone test! I can send the original bios!

These are the Fermi products that can possibly be modded for GOP/UEFI;
