Bios mod for Asus G73SW with GTX 780M DELL card

[fabri1983]

Hi all.
I'm trying to update my ASUS G73SW laptop with a new GPU card. 
Originally it comes with the great GTX 460m, which still nowadays runs AAA games (OpenGL 4.5 and DX11, medium and high settings, 1600x900 resolution).
I own a GTX 780m DELL card bought 6 years ago with the intention of doing the upgrade, however circumstances of life made me to concentrate only in work (IT) and the project was forgotten.
Now I'm taking back the project again. That's why I come here for help.

Is it possible someone of you could help me in modding the attached BIOS (info extracted with BIOS Backup Tools 12.2) to support the GTX 780m DELL card?
