I found ASD terribly annoying on my previous 2015 M4 and also coded it out. On that car, it was very noticible. Not the same case on the M4cs.

Agreed with his opinion.
I think they improved it vastly via software updates (M4 base). I have canflap valve controller that can also control ASD. I leave it on for sport+ mode and off for efficient to compare it easily. The difference is not much, just slight amplification. I actually like it on now. People wouldn't know it has ASD through speakers unless they are told so. Removing charcoal filters might have increased natural volume as well.
