Might try rain-x. I found it helps to keep my headlights clear, and no fogging on my other cars.
ITs not just ice build up that's a problem in winter. Coating with road salt/sand/grime is a big problem too especially at night. That's why a lot of cars had headlight washers/cleaners. They make a big difference on the grime/ice. Maybe rig up some extra tubing from you windshield washer sprayer to spray on the headlights, if its a constant problem. I know some older rams had headlight washers as an option. Don't know if the 2019+ had it as an option, to retrofit. Also parking in a warm garage keeps the ice buildup down.
Otherwise your stuck stopping at a gas station using the windshield cleaner on your headlights. Its what I do if the vehicle I'm driving doesn't have headlight washers, especially at night when you can't see crap from the headlights being coated with grime.
