The problem seems to be that the modesetting Xorg driver binds to the NVIDIA GPU for some reason. A workaround could be to force the NVIDIA Xorg driver. Create /etc/X11/xorg.conf.d/90-intel-nvidia.conf:

# Adapted from https://download.nvidia.com/XFree86/Linux-x86_64/460.32.03/README/randr14.html

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "intel"

    Option "AllowNVIDIAGPUScreens"

    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"

and reboot, and try prime-run again.
