How can I disable the upload data UI as a workspace admin to manage users’ ability to upload data securely to a Delta table or Databricks File System (DBFS) directly from the homepage, the Data tab, or the File menu in a notebook?
As a workspace admin, you can disable the upload data UI by following these steps:

1. Go to the settings page.
2. Click the Security tab.
3. Click the Upload data using the UI toggle.

Disabling this setting prevents users from uploading data securely to a Delta table or Databricks File System (DBFS) directly from the homepage, the Data tab, or the File menu in a notebook. However, it's important to note that this setting does not control programmatic access to the Databricks Filesystem, for example through the DBFS command-line interface.
