Cloudflare return with name servers

Hello, I need cloudflare to return nameservers to the company that bought the domain, a person who was a partner is using my domain in cloudflare. Therefore, I have no control over my domain’s DNS through the domain registrar.

Cloudflare can not set your name servers. Only your domain registrar can do this. It also sounds like you don’t have access to the Cloudflare account with your DNS records, correct? Because if you did, you could manually edit your DNS records.
