Problem

There isn't an option to (completely) disable the Company Hub feature.
Even if the Company Hub is not Published to end-users, the option remains visible to Site and Product admins.

In the documentation, there are instructions to Deactivate it (https://support.atlassian.com/confluence-cloud/docs/create-and-customize-a-company-hub/#Deactivate), but that only applies to cases when there was a published Company Hub that admins want to "unpublish". The "Company Hub" option remains visible in the top navbar for Site and Product admins.

Suggested Solution

To have an option to completely disable the Company Hub feature.

Why This Is Important

Company Hub is a feature that could be useful, but it would be helpful to have an option to turn it off and prevent it from being inadvertently published by some admin by mistake and becoming visible to all users causing confusion.
