DNSSEC is an authentication mechanism. It does not encrypt queries or responses.

You might be thinking of DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT).

There's also DNSCurve.

DoH and DNSSEC don't use ECH (encrypted client hello)

From what I remember, only DoT uses ECH

ECH can be used regardless of DoT, DoH, dnscrypt, or plain as long as your resolver passes HTTPS queries.
