Bios Mods -The Best BIOS Update and Modification Source

Hi. Just wondering if a bios mod is possible on this. There is no option to select onboard graphics or pcie graphics card. I have the latest bios, and the option isn't there. Just wondering if this option can be enabled. If so, I can upload the bios file. Thanks in advance.

Since posting this request, I've managed to sort it. I extracted the bios, edited it, and enabled the primary VGA adapter option. If anyone needs help with this, I can show you how to do it.
