I am using CentOS 7. I want to check whether remote web server supports TLS1.3 or not.
I have tried through nmap but till date, nmap (version 7.80) doesn’t supports TLS1.3
Is there an easy way to check for that?

I am pretty sure openssl (you need at least version 1.1.1) is able to do this.
openssl s_client -connect www.example.com:443 -tls1_3
