Schedule Waterfurnace Heat Pump On by Time of Day

We have a Waterfurnace heat pump for radiant floor in our home. It has a 120 gallon storage tank. By way of purchasing an EV, we now have lower electricity rates during the nighttime and morning hours. I want to maximize the time the heat pump is running during the times of lowest rates.

Anyone know if this is even possible?

And, if so, any guidance about how to begin?
