Hello,
The following document should provide information regarding DPE Configuration for Databricks integration:
https://docs.ataccama.com/one/latest/configuration-reference/databricks-configuration.html#databricks-job-cluster-configuration

I should mention that depending on your requirements you might want to configure the Databricks side of solution differently. Access Modes on the Databricks enforce quite a few limitations and can restrict you options you have in terms of authentication or access to Unity Catalog:
https://docs.databricks.com/en/compute/access-mode-limitations.html

One of the limitations that is worth mentioning is that Databricks Runtime v 13.3LTS is the lates one our platform supports.

I hope this information is helpful.
Ivan
