You will not break anything. Audi includes it with the stock ZF8 tune.
To enable AMAX:

S-mode, traction control off, steering straight, foot on brake pedal, floor gas pedal, release brake pedal. As MSq5 said, once engaged you’ll notice a difference.

Some of the guys tuned with HP Tuners on the ZF8 TCU are running “rolling AMAX” so they don’t need to come to a complete stop to have the AMAX type shifts.
