Question Turn on onboard graphics in BIOS

[AstralB3AST]

I have a gigabyte GA-78LMT-S2 motherboard and a GeForce graphics card. One monitor is plugged into the graphics card and works great. I have a another monitor that is vga and have to plug it into my motherboard. Every thread I read says that I need to turn back on my integrated graphics to allow my second monitor to work. However I can not find the setting within the bios to change this. Please help and thank you.

Edit:
I was able to turn on my onboard graphics but the monitor is still not being detected
