No, you absolutely cannot do this safely. Tesla v3 and up superchargers use liquid cooled cables AND CONNECTORS. There is no NACS connector that can reliably and safely pass over 500A without danger.
In theory you could go do this with V2 and older but they are increasingly rare. If you are not an electrical engineer, you are in actual serious danger of attempting stuff like this! The A2Z adapters also are not designed with a proper mechanical interlock, so could cause an arc flash event if disconnected under load! I have reported this to both A2Z and the NHTSA.
