I coded out ASD on my 2020 M2C, creates an annoying hiss / faint buzz through the speakers which I can hear when I open the car door and sit down in the drivers seat. However if I then turn the car off, make sure its fully powered down, then turn it on again it often goes away. Weird.
I have the ASD bypass cable on my desk ready to install.

Unplug the speaker behind the iDrive screen, it will help tremendously with the sound quality. That center speaker BLOWS.
