Check this site with VIN decoder for Tesla:
Tesla VIN decoder.
The 5YJ, was the reference from Fremont factory, until 2021, the 20222 model now has a diferent code its 7SA.
If you check in the Model X waiting room you will see all the vins now start with 7SA.
If we use the decoder we have:
5YJ | X | C |AE4XGF0068xx
before 2021 model | Model X | 5 door* |
* typicaly Model X
Acording to LucaRiv signature he ordered a Model S, yet he got a Model X VIN, so maybe he have a Model X and the VIN is from thar car.
I'm sorry but i don't think its legitimate.
Edit:
Here is an example of a recent VIN from a Model X:
Refreshed 2021+ Model X and Model X Plaid waiting room
