Add configuration options for notifications

**Feature request**
It would be great to have export for services.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_export` with default `false`.

No file or test is named in the issue; start by locating the configuration entry point and the service-export handling. Confirm how enable_export is read and where its default is defined, then verify that it defaults to false and controls export behavior.
