Bbwitch no suitable _DSM call found

Hi, I am trying to setup GPU switching on Asus Zephyrus G14(AMD Integrated GPU, Nvidia Geforce 1650). I installed optimus manager which was successful and GPU switching worked. After that I tried to setup Nvidia power management using bbswitch. I installed bbswitch-dkms-git from AUR, however I cannot get it to load. The system is running on kernel 5.15.19-1.

Modprobe output:

$ sudo modprobe -vvv bbswitch
modprobe: INFO: custom logging function 0x55c3b956d7f0 registered
insmod /lib/modules/5.15.19-1-MANJARO/updates/dkms/bbswitch.ko.xz

modprobe: ERROR: could not insert 'bbswitch': No such device
