[REQUEST] HP Pavilion P7-1414 Dual Graphics BIOS

[Reduce_]

I got really excited to try out dual graphics once I managed to get my card. However, to my disappointment, HP stupidly disables the onboard when I have a graphics card in and results in no dual graphics. Is there any way I could change that setting? I believe that in the original bios that came with the computer there was Advanced>Device Options>Integrated graphics, but I can't seem to find where that bios link exists as v8.18 still doesn't let you access that setting (and I can't install it for some reason as it says my computer isn't supported)
I did see a similar post from 2014, and used Access Advanced settings through EFI shell but I can't seem to actually do anything in the shell. 
Any help would be appreciated!
