Permanently remove iphone from list of available microphone devices on mac

Ever since the latest update, I have seen that whenever my iphone gets near my mac studio, suddenly a black screen appears with notification that "you can disconnect to remove this iphone from the mac microphone list" and a disconnect button in red.

This is extremely annoying as I never intend to use my iphone as a mic for my mac(I already have a quality microphone plugged in). And thats not even the main reason. The main reason is that whenever that screen on my iphone appears, then whatever is the active app gets terminated.

If my iphone screen display is off during the time when iphone mic is connected, it does not turn on the screen even after hitting the power button or the home button. It takes 4-5 seconds and multiple attempts to resume the screen.

This is really terrible and I need a way to prevent this auto connection. Tried the MIDI option, but I don't see a disconnect button or a way to permanently remove iphone microphone from the list.
