Hi @Praveen Thank you for sharing your concern here.

You are looking into the Catalog on the account console, but according to the document, you have to do this in the Workspace Catalog UI.

Please follow the below steps,

1. Log into any of the workspaces that metastore is attached.
2. Click the Gear icon gear icon at the top of the Catalog pane and select Metastore.
3. On the Details tab, enable External data access. 

I am also attaching the screenshots for your reference,

Please leave a like if it is helpful. Follow-ups are appreciated.

Kudos,

Sai Kumar
