Change DNS servers on domain registered on CloudFlare

I am in the process of switching my domains to cloudflare registration. Figured it would make my life easier to manage everything in a single place.

For the most I am happy with this decision however I am hosting a few sites on siteground -
and I would like to change the DNS servers to siteground DNS servers.

If my domain is registered with cloudflare how do I change my DNS servers?

The short answer is you can’t. Longer answer is there are options on the paid plans for custom name servers, but that won’t get you what you’re looking for. This has been discussed a few times on the site if you want an even longer answer with the details.
