Unable to change brightness on Manjaro-kde Ornara 21.07 with nvidia dirve 465

Hello there,
(Just reinstalled) I found out today that I cannot adjust the brightness of my screen. I think the probable reason is Nvidia driver 465. I installed other versions of linux and tested it (nvidia version is below 460) and there is no such problem.

This is a supplementary explanation. Because the open source version also has this problem, I used to install the closed source directly to solve it, but now both closed source and open source have this problem.

CPU: Intel i7-8750H
GPU: nVidia GP104BM [GeForce GTX 1070 Mobile]
laptop: Predator PH517-51
os: Manjaro-kde Ornara 21.07

I know that the official manjaro command to install the graphics card is:

sudo mhwd -a pci nonfree 0300

But how do I specify the version to install, (and how to change the version) like change to Nvidia-460
Thank you.
