Just run MCACC. That should calibrate and take care of the trims, bass management, distances etc. Do a quick double check on everything and your good to go. I'm sure there is a setting in the receiver to disable the MCACC equalization. To use or disable that equalization is purely ones preference. I'm not sure exactly what it is called or where to go in the settings for it because I am use to Denon and Onkyo receivers which employ a different technology.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
