If you can run PHP scripts and your system has cpanel access, you might benefit from using CertSage instead of manually running Certbot on your personal computer.
It's a PHP program that you can upload, and just go to the page to handle getting the certificate and installing into cPanel. You'll still have to do it manually every couple months, but it might be slightly easier for you. (Though on the other hand, if you have a process that works for you already, I could understand not wanting to mess with it.)
