How to disable /<username>.keys URLs?

Like GitHub, GitLab displays public SSH keys for users to unauthenticated visitors at URLs such as https://gitlab.example.com/.keys

Unlike GitHub, GitLab also displays the full profile name of the user.

For a private self-hosted instance such as ours, we’d prefer to disable these URLs (or at least remove the user profile names) to reduce unnecessary information leakage about users.

Is this possible?
