Hello @djburnham, good day!

Did you try using this API: https://docs.databricks.com/api/workspace/users/list

This API provides a list of all the users in the workspace and their entitlements. You can get the list of users, parse through each user's entitlements, find out who has unrestricted cluster creation permission, and then create a report on it. I believe this will help you. Please share your thoughts on this.

Best regards
