You can't disable the daytime running lights (DRLs) on a Chevy Beretta by a simple switch or fuse pull like some other vehicles. The Beretta's DRL system is integrated into the car's electrical system and isn't designed to be user-disabled. Any attempt to do so through modifying wiring or fuses could be dangerous and potentially damage the car's electrical system.
Therefore, there's no safe and reliable way to turn off the DRLs on a Chevy Beretta. You'll have to live with them as a feature of the vehicle.
