There are still some old V2 superchargers around that support Tesla’s old proprietary, modified version of the Type 2 connector (the top part of the CCS2) that was used on older Model S/X. But even those superchargers were modified to have the standard CCS2 connector added to them.

Do Superchargers in Europe use CCS2?
Yes, I believe they do.
