NVENC works on win10 but not on Linux

I have a GTX 1050ti which should be able to run NVENC perfectly, it runs flawlessly on windows but when i switched to Linux i couldn’t use it, tried so many fixes but got no results. I’m now on Arch but a few months ago i tried using Pop!OS and got the same error. The reason might be my mobo being too old, but i don’t know why would it work on windows and not on Linux

FFMPEG Output when using nvenc

Your mainboard has a nvidia chipset which the linux driver mistakes for a nvswitch system.

Are the results the same when you apply this patch - GitHub - keylase/nvidia-patch: This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs. ?
