You can just unplug the Daytime Running Light Module, sounds like yours is faulty, and all other functions will work the same, except you will lose the high-beam indicator and the E-brake indicator lamps on your instrument panel, as they work through this module. It is located on the driver side just behind the front bumper, in a void between the front bumper and the front fender well. Headlights should continue working, High and Low.
