Stash disable read for repository

We have a team with write permission for Stash project (and this team has several repositories). In this project, there is one particular repo with confidential data and password hash algorithms. Because of compliance issues that repo should be visible only to two developers, listed by name.

Project has default "No Access policy" and "write policy" for a developer team. Repository has disclosed list of devs (with read and write access) in repository permissions. Unfortunately anyone with write and read permissions for the project is able to see this particular repository content.

Is there a way to restrict an access to this repository?
