TLS 1.3 Secure Renegotiation not supported
Yes, since TLS1.3 forbids any renegotiation, supporting rfc5746 with it would be meaningless, and rfc8446 doesn't even mention the possibility. 

Of course an endpoint that supports both 1.3 and lower versions should (in the 2119-capitalized sense) use 5746 for sessions that negotiate a lower version, and (AFAIK) OpenSSL does.
