Output iGPU on dGPU?

Hello people,

I've managed to get my Hackintosh working, now I'm trying to see if I can make things better. I have a GTX 1060 and an iGPU (UHD630). The GTX being useless, I used an HDMI cable to plug the monitor in the motherboard HDMI port and disabled the GTX in opencore. That means two cables between the monitor and the PC since I'm using DP with the GTX 1060 for Windows.

Is there a better way to do this? Would it be possible to still use the UHD630 but output it on the DP port of the GTX 1060? I think I've read something hinting at this, but I can't figure it out.

Thanks!
