The safety inspection, often thought to get supercharging back, is actually just to say it's safe enough for their people to work on, but not safe enough for superchargers. Apparently their people mean less to Tesla than their supercharger stations! There is a separate inspection that is available for the model 3 and model y, and some people have had it done for the model s, that will allow you to supercharge once again. They even leave the free unlimited supercharging in place. Don't think anybody's had it done for a model X yet. Still, you can try to schedule a service for that purpose and see what they say. I, for one, would love to know the answer you get!
