Help with Multi Monitor AMD APU and NVIDIA GPU

I am a novice linux user and just started using Manjaro with Gnome DE on my dekstop PC for coding purposes, now I am trying to do a multimonitor setup. I have an AMD APU Ryzen 5 5600G and DGPU Nvidia 1660 Super. My current gpu driver is video-hybrid-amd-nvidia-prime. My primary monitor is connected to my APU which works but since I am out of HDMI ports I am unable to use the Secondary monitor on my APU and tried to connect it on the HDMI port of my Nvidia DGPU but it doesn’t work. I have read somewhere that it is because of nvidia proprietary drivers unable to be used as output sink. I have also read that I might be able to do a reverse-prime setup making my nvidia gpu as main output but I don’t know how to do that as I am really not familiar with xorg configuration stuff.

I tried using the open source drivers video-linux since I am not going to play games on linux which works for multi-monitor setup but when I plugged the monitor to my DGPU the screen is glitching so I decided to go back to using hybrid drivers.

I hope someone can help me, I will be willing to learn how to do configuration.
