Configuring DNSSEC for a domain https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/domain-configure-dnssec.html

Amazon Route 53 supports DNSSEC for domain registration.

However, Route 53 does not support DNSSEC for DNS service, regardless of whether the domain is registered with Route 53. If you want to configure DNSSEC for a domain that is registered with Route 53, you must either use another DNS service provider or set up your own DNS server.
