Cloudflare in subdomains

How can I put “cloudflare” to my subdomains, or how can I put the “ssl” free of “cloudflare” in my subdomains?
Thanks for your answers.

Cloudflare doesn’t allow subdomains to be registered separately, Cloudflare will only provide their services if you can provide your own registered domains.

@Admin Hm but I use it already, we’ve wasted much time to get the answer bruh…
