Broken laptop keyboard, how to switch graphics card?

So long story short, my laptop keyboard is broken. I hardly ever use it since I got a nice mecha keyboard. But then I run to the issue that I cannot disable or enable integrated graphics card because the FN + i/d GPU is not working anymore. I took a look at the BIOS setup but I don't think I could enable/ disable integrated card with it. Anyone know a work around for this issue? I really appreciate any input. I could think of borrowing a working keyboard and just plug it in to enable the integrated graphic but I would rather have something software related. Maybe an on screen keyboard or stimulation keyboard for example? Thank you for your help : ).

 

There should be a bios option IIRC, check again but perhaps an unlocked bios reveals it.

 

You must have an unlocked BIOS. go over to the second advanced menu, find "video", and change seeting from "SG" to "PEG" for discrete card only or leave on SG/IGFX for intel GPU.
