Excuse me, two monitors are connected to amdgpu and nvidia.

You can try to use https://wiki.archlinux.org/title/Multihead#Xinerama - but that defies the xrandr extensions and several clients won't respond all that well to thise nowadays.
Check

xrandr --listproviders

iffff this is a hybrid stack and you can redirect the ouptus, you can run the X11 server on one GPU and use the other one as CRTC hub (though I'm unsure why one would do so unless this is a notebook w/ few hardwired outputs)

Alternatively you can just run two different desktop environments (one on either head)
