Or Darumaka? And is there a way to get a replenishable amount of them?
You can get Unovan Darumaka by trading with someone online, or by trading with an NPC on the Isle of Armor. Do note that the NPC will ask you if you can trade any Galarian form for a standard form, so you being offered Darumaka is not guaranteed. You'll need a Galarian Darumaka for this.
Source: Experience
You have to trade, there's no way to get them naturally in-game. However, once you get one, you can have it hold an Everstone and place it in the Daycare. The Darumakas produced will be Unovan, not Galarian.
Hope I helped!
