Hi @anvil_panow, thanks for posting.
It sounds like you would like to update the domain name that is being used with your GoCentral Website Builder. You'll need to update your GoCentral plan to use your domain, and then update the IP address your domain name is configured to use.
See details in this article:

You generally would not change nameservers for this.
