The configuration directives that are relevant in this case
sslVersion = TLSv1.2

Keep in mind that TLS 1.2 is not widely deployed. So if you need
backward compatibility you might want to enable SSLv3, TLSv1, TLSv1.1

The documentation in the link you provided should allow you to tweak the ciphers you want
