All V3 and V4 superchargers (you can tell because they have 4 pedestals per cabinet, so labelled #A-#D), have CCS (PLC) modems and are capable of charging any CCS vehicle Tesla decides to allow with a simple mechanical (no electronics) adapter.
V1 and V2 superchargers only speak Tesla's proprietary Single-Wire CAN protocol, and Tesla will not release this for other makes, though it is possible to upgrade these by replacing the electronics in the pedestal to include a PLC modem, but I have not seen this "in the wild" yet. Tesla so far has used Plug-N-Charge certificates to restrict CCS charging for 3rd parties, but word is that some GM cars will not support this, so I don't know if they will open it up for these cars or not.
