Nameservers - Domaint -> web server

I want my own nameservers (ns[dot]mydomaincom) so I can use them to point to my web server. I created “personal nameservers for my domain” also called “glue records” and have it pointed to my web server’s IP address. In my registrars custom dns fields I put “ns1[dot]mydomaincom” and “ns2[dot]mydomaincom

I just want to setup an authoritative dns server on my Hestia webserver.

So you are saying if I want to have “ns2[dot]mydomain.com” I need to setup a second server? What if I don’t have access to another server?
