Nvidia Drivers Installed but mhwd doesn't show them

So I was looking after a solution for why my hdmi graphics card sound was not being detected and I stumbled upon a strange finding
on my inxi -Fxxxxa it shows the following:

when I look further I see that I'm using chaotic nvidia drivers:

❯ pacman -Q nvidia                                                                                    ─╯
chaotic-nvidia-dkms-tkg 460.67-1

And then for the cherry on top of the cake the mhwd gui shows this:


and this when only dangerous configs are selected:

What should I do ? should I use the auto install since I'm using the lts kernel ?
another interesting thing is that I can run games while using the external monitor using the nvidia gpu, but I think I have some problem between the kernel and the driver where the sound card of the gpu is not being enabled to be detected by alsa

That's because

If your GPU is working, nothing.

Well, Glad for your response, and you were right, I found that mhwd actually disables the gpu's audio source on the rules for whatever reason. I found it while looking for the same problem with ubuntu users on this :sound - NVidia 460 update disables HDMI audio output - Ask Ubuntu that also linked to this: No HDMI Audio on Nvidia 1660 Super (Driver 460) & Ubuntu 20.10 - #5 by duffleda - Linux - NVIDIA Developer Forums where I found what I was going to have to look for, but instead of it being under /lib/udev/rule.d it was on /etc/udev/rules.d/90-mhwd-prime-powermanagement.rules where the second line was uncommented

# Remove NVIDIA Audio devices, if present
#ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x040300", ATTR{remove}="1"

when I commented and restarted the laptop the hdmi output worked and shows on the inxi!
