How to Hide the Relationships Tab in a Tree-Style Relationship Application

I have a Relationship-type application configured with the Tree style. I need to keep the record detail section displayed on the right side, but I want to hide the native Relationships tab that is automatically included in this application style.

I can control the visibility of any additional tabs that I create, but I have not found a configuration option, field dependency, or action that hides the native Relationships tab.

Is there a supported way to hide only the native Relationships tab while retaining the detail section and the relationship tree on the left?

Screenshots of the application and its Application Builder configuration are attached.

@lpopovici I looked into this further and it does not look like this is supported. Feel free to submit an official enhancement request via Freshdesk (include a link to this post).
