With xrandr you can make your own profile for both monitors but inside wayland session not really. Even nvidia-settings works not right inside wayland-session. (my mind)
Install wlr-randr to config your monitors.
sudo pacman -S wlr-randr
over konsole run wlr-randr to config.
even possible :

Test it in a x11 session.
Perhaps you need for the x11 session file xorg.conf in /etc/X11/xorg.conf.d.
Use nvidia-settings or make your own file. Reboot and ?
