Welcome to Manjaro

Please when posting try to provide good information about your system as suggested in this post:

Now, I suspect that you will need Nvidia-455xx-prime to get things going.

  1. In terminal you could type sudo mhwd -a pci video-nvidia-455xx-prime
  2. Install optimus-manager to get the ability to choose only Nvidia, can look at the docs here and GitHub here. NOTE: Check the installation procedure on these two pages.
  3. You could install optimus-manager-qt from pamac (the add/remove app)

In order to get these settings running, you will need to reboot.
Optional: Have optimus-manager start when computer boots

IF you use steam you might need to install vulkan-mesa-layers so games launches.
