I don't think it's accurate that there is "no way" to "prevent your mac from using the headphone's microphone." There are several workarounds like creating an Aggregate Audio Device in Audio MIDI Setup [0] or disabling HFP [1]. I wish you success with your paid utility though.

I popped in here to post this. The aggregate audio device setup in the Midi setup assistant works really well for me. There is some loss in quality still, but definitely not as bad as before.

It also solved a problem I was having where the input volume would progressively get quieter as I was speaking making it so no one could hear me on calls.

Yep, I forgot to add it and I'll update the post providing that option.

The reason I didn't add it is because I tried it and didn't work for me, so I just forgot it was even an option.

Thanks for the heads up!

Neither suggestion in your links work. macOS still automatically switches to my AirPods mic when I connect them.
