How to prevent Android Auto from establishing Bluetooth connection?

I have a 2019 Hyundai Kona which has support for Android Auto. You need to connect the smartphone via USB cable to activate it.

My wife does not like Hyundai's navigation system so I thought about using Google Maps via an unsused phone. Idea: the smartphone is permanently connected to the Hyuindai and can be used for navigation (it has an Internet connection).

My problem is that Android Auto establishes Bluetooth connection to the Car's system upon activating. I don't want that because I want to use my regular phone for calls.

What would be the easiest way to permanently disable Bluetooth on an Android smartphone? The phone could be rooted, there is LineageOS on it.

There is an option to keep Bluetooth off during Android Auto in the Android Auto settings on your phone. But I never tried that option.

    I checked on Android Auto 7.8. It seems that Google removed this option.
