Thank you for tip. It was relatively straight forward and simple once I found the guide based on your lead. I managed to clean some things up in the process.

Something like this .. you may need to specify the curve depending on your version of certbot -->

certbot renew --dry-run --key-type ecdsa --cert-name example.com --force-renewal

Here's the reference to help anyone else taking the same path -->
