Cloudflare authenticated origin pull


I’m trying to setup cloudflare’s authenticated origin pull to prevent someone from bypassing cloudflare protection. Is it possible with cyberpanel and openlitespeed?

If it’s not possible to use authenticated origin pull, can I setup iptables firewall to block direct access to ports 80 and 443 and only allow connection from cloudflare ips?
Will this firewall rule break letsencrypt for the server hostname?

Thank you.
