Change dns server

change dns server
My domain name configuration dnssec has not been configured for two weeks, (via: Registration Transfer In - DNSSEC stuck at “DNSSEC is pending - DNS & Network - Cloudflare Community) how can I change it to another dns server, because the domain name is registered in Cloudflare, it has not been transferred out for 60 days, and now I want to try to change it to a non-Cloudflare one dns server, how to modify it?

If you mean you’re using Cloudflare Registrar, you cannot change nameservers.

Registrant agrees to use Cloudflare’s nameservers. REGISTRANT ACKNOWLEDGES AND AGREES THAT IT MAY NOT CHANGE THE NAMESERVERS ON THE REGISTRAR SERVICES, AND THAT IT MUST TRANSFER TO A THIRD PARTY REGISTRAR IF IT WISHES TO CHANGE NAMESERVERS.

so,how can i do config dnssec?
