Feit Smart Dimmer Switch - Tasmota Firmware Question

These are fantastic switches and very affordable too, and available from Costco for $20 a 2-pack. To get to work with Home-Assistant, they need to be flashed with a special tasmota firmware, and there are few posts about this.

However, should one need to revert back to the original firmware, is that feasible at all?

Any information would be appreciated.
