Automatic headlights still come on automatically?

We have the SUV listed above police packaged vehicle. When the vehicle is placed in gear, the headlights come on automatically. We've checked the DIC settings and set the headlight switch to "off", yet the lights still come on automatically. We tried setting the parking brake as well, but no matter what, we can't seem to figure out how to disable the headlights from turning on while in gear (day or night).
