Hmmm, thought it would.

I figure the rear one's not turning off might be more safety than anything.

Maybe just try to set the front ones as quiet as you can with the least annoying frequency.

I swear I thought there was an on/off function in the MMI though.

My dad's RX450h has the front park sensors. I have only ever seen them go off once when he was driving (they are always activated) and it was because someone walked in front of him when he was waiting at a stop sign to turn. I have a feeling it would be a little more annoying with the Audi as the Lexus only has 2 sensors on the corners in the front (4 in the rear), whereas the Audi has 4 sensors on the front (the Lexus will not detect directly in front of you, but rather at a slight angle).
