Tyre changing on an EV should be no different to an ordinary car. If your tyres have acoustic foam inside, some garages might be hesitant to peel back the foam to seal a hole but some are happy to do them.
Do you have a spare wheel?
If not, if the screw isn't quite all the way in, maybe screw it in a little further so the head gives a bit of a seal slowing the air leak until you get it fixed
