If you are referring to the freezing up of the crankcase ventilation valve (CCV), then not directly. You would need to drive the vehicle longer once it is warm, to boil off the condensation that collects. An engine heater isn't going to get rid of the condensation, but if you are always doing very short trips, then starting off somewhat warm can help. The real solution is to keep an eye on the CCV, and clean it out periodically if there are signs of the condensate building up under the oil filler cap.
