Trying to get Onboard Graphics and External Graphics Enabled Together

[dundundunnn]

Hi! Today I tried to hook up a second monitor to my computer that I built myself...but when I went to plug my monitor to my motherboard HDMI but I get No Display has been Found. I thin did some simple googling and figured out that my onboard graphics are probably not enabled and I need to do that in my BIOS. The only problem is I figured out where to enable my first priority graphics which I have set to PCIe 1 but I cannot figure out how to get both my onboard and external graphics card to work together so I can plug in my HDMI cable to my motherboard.
My Specs:
Graphics Card- NIVIDA GTX 1050 Ti
CPU- Core i5 6600k
Mobo- Gigabyte H170M DS3H

If anyone can show me where in the bios to enable this or tell me if my motherboard is just not capable of doing this that would be great thanks!

Again, this is very much motherboard specific. Some will allow you to. Others will not.
