The clunky auto headlight feature is the same for all trims (except LX). The only setting that you can change (on Touring models) is for how long you want the headlights to remain on after the key is off and the driver's door gets closed (0, 15, 30 and 60 seconds). The EX, EX-L ones have 15 seconds as the default.
Having said that, it does not mention anything about being in AUTO mode and unlocking and opening the driver's door in the dark, which also turns the lights on, but try setting it to zero seconds, it may actually do what you want.
See owner's manual (2011 models), page 93 and 115.
