I gave up many times trying to change gpu and finally it’s very possible that i used only optimus.
> pacman -Qm
ceph-libs 15.2.14-6
google-chrome 106.0.5249.103-1
manjaro-documentation-en 20181009-1
manjaro-firmware 20160419-1
visual-studio-code-bin 1.72.0-1
remove these:
pamac remove ceph-libs manjaro-documentation-en manjaro-firmware
did you rebooted after you uninstalled optimus?
post again output from:
ls /etc/modprobe.d
find /etc/X11/ -name "*.conf"
No, i’ve done it now.
> ls /etc/modprobe.d

/etc/X11/mhwd.d/nvidia.conf
/etc/X11/xorg.conf.d/00-keyboard.conf
/etc/X11/xorg.conf.d/30-touchpad.conf
so if you rebooted now, post again output from:

Thank you very much 
now that you have properly working nvidia, you can install optimus again if you wish
