any chance my car’s alive?

was taking the best afternoon nap during the storm, and woke up to find my car submerged about 3/4 of the way up the wheels. water got in the car (carpets wet, but there’s none standing), but my big concern is that the alarm was going on and off, my windshield wipers started and stopped a few times, and the headlights would flicker. seems like an electrical thing, so i disconnected the battery so it wouldn’t keep freaking out. it’s a 2019 chevy SUV- in y’all’s experience, any chance it’s fixable?
