Well I need to RTFM !
The solution appears to be https://github.com/theforeman/puppetdb_foreman.
Go to Administer > Settings > PuppetDB and set puppetdb_address with your PuppetDB address, puppetdb_enabled to either true or false if you want to enable or disable PuppetDB integration. Obviously you will need a PuppetDB instance at the address you provide.
Alternatively you can put your settings in config/settings.yaml . Please keep in mind these will be overwritten if changed in the application, and if the application is rebooted, YAML rules will overwrite again your manually changed settings. Hence passing your settings in this format is discouraged, but allowed.
