DNSSEC is a means of authenticating the data receives was not tampered with, such as MITM attacks, thus ensuring data integrity. It uses PKI but it's not an alternative to DoH or DoT which encrypts the DNS traffic, either over HTTPS or TLS, providing confidentiality.
DNSSEC can be used in conjunction with DoH or DoT to achieve the Security CIA triad - Confidentiality, Integrity, Authenticity.
