Changing to onboard for Hack, remain on nvidia for windows?

Hey all, Firstly, I am a little rusty here as I have never tinkered with my Hack since I got it all running over a year ago. I have just upgraded my GPU to an nvidia RTX card and now I cannot get full resolution to my monitor. I’m guessing the nvidia web drivers are not compatible?

So I’m booting up using my onboard output via HDMI while still having display port connected to the SAME MONITOR for when I boot windows. This was a bit of a pair as I had to set this up in bios to use onboard and ignore dedeicated and this is a bit of a pain to have to do each time I switch system OS so I would like to know if there is a way to get the Hack to ignore the nvidia card and always choose onboard so I don’t have to force it via bios?

Hope this makes sense!

I am still on high Sierra by the way.

Many thanks.
