iGPU Triple Monitor Setup

Hello everyone, I recently set up my 3 screen setup on my computer by enabling the integrated graphics card on the Bios. On windows 10 it was plug and play, but I can't figure how to get it going on Manjaro and I can't seem to hit the right post with the information needed either. I read somewhere that it worked out of the box for someone with the nouveau drivers but it wasn't my case, although it was as close as I got (for a split second everything on my screens was messed up but there was some stuff showing on the screen plugged on the iGPU socket. If nouveau is the only option I'll take it but I would love to make the best out of my gpu using the nvidia drivers instead. Btw, I'm running an RTX 2070 with one screen connected on DP and another through HDMI, then on the on board graphic card I got a screen connected through HDMI. I can provide any other relevant information needed.

Sorry for the wall post and thank you for your time!
