Either change host or automate submission of cpanel's certificate. This could need modifying an ACME client. It might mean letsencrypt is not ready for you (yet). I'd wait for your host to update its cPanel (unless you absolutely need https, then I'd either change hosts or buy a certificate elsewhere).
