The Philips Hue (I use this)/pretty much any smart lighting system has lights in it range that can shift white balance and most have some kind of software to schedule the shift over the course of a day, often in the form of an iOS/Android app.

These things are super easy to buy generally speaking - Best Buy/Home Depot style stores stock them, as well as pretty much all major online retailers. The Hue system is pretty popular right now.
