Use Cloudflare as a nameserver for only a handful of subdomains?

Hi, a very large organization wants to set up Cloudflare’s DNS for just a handful of subdomains on their domain. The rest, they don’t want to touch.

Let’s say they’re, but they don’t want the entirety of’s DNS zone to be hosted by Cloudflare. They only want the subdomains,, and to be managed by Cloudflare.

Normally, I’d add NS records for those subdomains on their original NS zone and point those to a different NS, but I’m not able to add a domain with a subdomain as a site in Cloudflare.

Is this possible with Cloudflare? With the free plan?
