When enabled (enabled by default for new installs) ISPConfig will automatically remove certbot/acme.sh issued certificates that do not get used anymore.

You can specify a list of domains that should never be automatically deleted. If you use certbot/acme.sh on your server outside ISPConfig you should list all these domains in the denylist otherwise ISPConfig will automatically remove the certificates.
