Is it possible to hide the Attachments region for a specific Document Type

Content

We don't want our users to attach anything to a custom document type "Attestation".  I need to hide the Attachment region when users create or update this document type, but have it available on all other document types.  Any ideas how I can accomplish this?

I tried various ELs (see a few examples below) but could not make it to work  what am I doing wrong?

#{bindings.SystemDocumentType.inputValue !='US_ATTESTATION'}

#{bindings.DocumentTypeId.inputValue != 300000411062743}   Pulled the ID from the Document Type Identifier field in OTBI

#{bindings.DocumentType.inputValue != 'Attestation'}

Is there another way to disable the attachments other than personalization?
