Yes, you can set up TAC (Databricks Table Access Control) even if workspace is enabled for Unity Catalog in Databricks.

Unity Catalog is an alternative to the Databricks Delta Lake table format and is fully compatible with Delta Lake. TAC allows you to manage access control to tables and views in the Databricks environment.

Once TAC is enabled, you can use it to control access to tables and views in the Unity Catalog as well as in the Delta Lake format.
