Create /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf:

Section "OutputClass"
    Identifier "AMD"
    MatchDriver "amdgpu"
    Driver "modesetting"
EndSection

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "PrimaryGPU" "yes"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"

Add to ~/.xinitrc:

xrandr --setprovideroutputsource modesetting NVIDIA-0 
xrandr --auto
