Using Helm Chart and External DB


I am looking to install Crowdsec on my Kubernetes cluster. I have been using the chart for a while with the usual SQLite DB but for a bigger deployment I’m looking to use a managed Postgres DB. I cant find anywhere in the Helm documentation on how to configure an external DB. I see here that we can configure some parts of the config.yaml but nothing is noted for the db_config portion I was expecting based on this documentation. Anyone had any luck attempting this?
