Howdy tries to use GPU with CNN set to false

[kalebealvs]

I have a Zephyrus g14 2022, an all-AMD laptop. From what I understand, howdy cannot use AMD GPUs, so it should never try to use that, but every time I use Howdy, it probes all my GPUs, including the discrete one. The problem here is that since I'm using dri_prime, the discrete GPU is almost always disabled, and enabling it takes quite some time, which creates a massive delay every time I use Howdy, to the point where I can type my password multiple times before howdy even starts the camera, not to mention increased power consumption for no good reason. I can verify that that's the case because if I completely disable my dGPU or enable it before using Howdy then there is no delay, also ROG control center notifies me that the dGPU is being enabled every time the process starts.

Is this behavior expected? If so, Is there a way to completely block Howdy from trying to use any GPU? That would be useful in my case since my iGPU and dGPU are both AMD and useless to Howdy.
