To install DNSOnly cPanel, connect to your server via SSH as the root user and run the following command:
curl -o latest-dnsonly -L https://securedownloads.cpanel.net/latest-dnsonly && sh latest-dnsonly
If you have an existing cPanel installation that you would like to convert to DNSOnly, the steps to do that can be found here.
