My experience trying to find an alignment shop might give you all the info you need to know (hint, it mostly matches what people have already told you):
1) First relevant shop I talked to that said they didn't have the tools necessary to follow all of the instructions their software provides for the alignment (these instructions came up based on VIN but included resetting and/or calibrating things that I've seen other sources say don't need reset/calibrated and also things that didn't even exist). Ultimately, they weren't willing to try.
2) Second relevant shop I talked to said "yeah, we can do it and have done others" but had to cancel when I showed up because their machine had been fried in a storm and their loaner didn't have the specs for it.
3) Third relevant shop I talked to said "yeah, we can do it" but ultimately found out they couldn't customize the specifications in their software, so they were limited to aligning it to the factory specifications. They were surprised by this because they'd never seen alignment specifications they couldn't customize.
FWIW, when I say "relevant" I mean I talked to other shops, but none they didn't want to work on Tesla and/or aftermarket, so there was no relevant information from those shops.
