Asus N53SN : disable Intel graphic card

Hello,

I am new to bios unlocking.

I would like to mod the American Megatrends BIOS (version 2.01.1204) on my Asus N53SN-SZ126V laptop.

There are two graphics cards on this laptop : an Intel HD3000 and a Nvidia GeForce GT550M. It is called Optimus technology.

The option I want and that is not in the original BIOS : disable the Intel graphic card so I can enable Nvidia stereoscopic 3D Vision in the control panel of Nvidia's drivers :
for the moment, I cannot enable it because I cannot assign the HDMI or VGA output to the GeForce GT550M; whatever I do, it is always assign to the Intel graphic card : I hope this will be possible when the Intel HD 3000 is disable.

Thanks per Advanced for your answer
