How to remove action suggestions from project page ("Add README" etc.)

Hi.

How do I remove buttons like “Add README”, “Add CHANGELOG” etc. from the main project pages (self-hosted GitLab CE 11.10.0)?

Update: I have found a corresponding open issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/45815
I wonder what the developer who introduced these buttons without a way to remove them was thinking. They are only slightly less annoying than an ad banner.
