Proper way for iMessage to work

EV Play has been great overall with very few issues for me.  The one question I have is about messaging through iMessage.  When I receive a txt, the Google system in my vehicle chimes that I received a txt and takes over, sticking iMessage in the background.  If you respond, it does so through Google.  I tried to turn off the Google Assistants ability to read txt messages to see if that would work, but it seems that disables being able to respond to messages in iMessage through voice.  What is the proper sequence to setup the system so iMessage is the sole messaging app eliminating the built in Google infotainment?

I have a Silverado EV with Android 14 infotainment.
