Definitely not this. Virtualmin calls `certbot`, and then does stuff with the resulting certs, not the other way around.

[Virtualmin has pre and post hooks](https://www.virtualmin.com/docs/development/domain-management-api/), though, so you can write scripts in whatever language you like (including bash shell scripts) to run before or after changes. Renewing certs is a change, and the hook runs. To know if it’s a TLS cert change, you’d check for `SSL_DOMAIN`.

There’s an example of copying certs for a service not supported directly by Virtualmin here: [Domain Management API | Virtualmin — Open Source Web Hosting Control Panel](https://www.virtualmin.com/docs/development/domain-management-api/#update-ssl-certificate-for-prosody)

So, you could base your post script on that, and then configure Virtualmin to run it in Virtualmin Configuration-\>Actions upon server and user creation-\>Command to run after making changes to a server
