You may have better luck asking that on a Sectigo or CertiNext community forum. This forum focuses on Let's Encrypt certificates.
While we often help people use Certbot, that's only very rarely for CAs other than Let's Encrypt.
Using a DNS or HTTP Challenge are the most common types used for Let's Encrypt. I'm not even sure which other kinds Certbot supports.
If you want help with a specific Certbot command please show it. Maybe someone will help out anyway.
The EFF develops Certbot, not the ISRG who manage Let's Encrypt. Again, we often help people use Certbot for LE but another option is to post an issue on the EFF's github for Certbot
They will almost certainly want you upgrading to the latest so follow the link rmbolger provided for the EFF's install options. Package maintainers do not tend to keep up with the latest versions by the EFF. There have been numerous improvements to Certbot, and the ACME Protocol in general, since your version was created.
