Modding bios for Asus N43SM

So I got an modded bios for my laptop, Asus N43SM, on this forum:http://forum.notebookreview.com/asus-reviews-owners-lounges/596426-asus-n43sl-sn-owners-lounge-54-print.html
I have Intel HD3000 and Nvidia Geforce GT 630M, using AMI Aptio bios
The modded bios unlocks most options, but the Graphics options aren't satisfied me. So I decided to look at the original bios and the modded one. Here's the screenshot of my bios's Graphics Config section:

Left is the original, Right is the modded one
I see that the interesting part is the 3rd " Primary Display " line, which has 5 options: Auto, IGFX ( obviously the Intel HD3000 ), PEG ( the GT 630M ), PCI ( dunno ), and SG ( Switchable Graphics ). Also the " Internal Graphics " too, which has: Auto, Enable and Disable.
My goal is to reach one of these resulst: either disable completely the Intel HD3000, or make an option to disable the GT 630M
Is it possible ? I'm kinda new to bios modding so I need some instruction or advice.
Thanks in advance
