Find your DNS provider in the list of modules (dns.providers.*) and select it. Download your custom Caddy …

And building Caddy with plugins is very easy. You can just download a build directly from Download Caddy with the plugins you need, or follow these instructions Build from source — Caddy Documentation which is as simple as downloading Go, downloading xcaddy, then running xcaddy build --with <plugins>.
