Inside a data type records edit page, is there any way to disable record deletion by pressing the delete button (at end of each record) and enable the deletion by importing file?

Best by role access control. Now I can disable deletion access on our xxx-Data class to disable record delete but can not allow it by importing, so importing file to delete is also disabled.

The delete button is dangerous as no double confirmation before deletion. Any way to add a double confirmation before deletion?
