Other brands let you recalibrate the ANC on an airplane. It's a thing. Do Apple not let you do this?

Other other brands dynamically do this, so you don't need to do any recalibration manually. Bose Ultra headphones, for instance, seem to do this dynamically all the time. You can tell this happens since the ANC slowly ramps up as you get a better seal on your ears.
