Change/set default output for calls on Apple CarPlay

I wear hearing aids connected to my iPhone 14 ProMax. When I receive a call, my hearing aids are the default output. I have 2 vehicles with wireless CarPlay. When I receive a phone call while connected to CarPlay, the audio used to automatically come through my car speakers. 2022 Honda and 2022 Acura.

The sound now comes through my hearing aids unless I manually change the sound source on my phone with each call.

Is there a way to set up the sound to automatically come through my car speakers? I’ve looked through the settings on both cars and on my phone and can’t find anything.
