Backup and other paths to NFS not working with root_squash and storage directories management disabled

I have an NFS share that I cannot set no_root_squash on because NetApp NFS does not support no_root_squash. When I try to set gitlab_rails['backup_path'] = '/gitlabdev/gitlab-data/backups' in gitlab.rb I get the following error:

  * directory[/gitlabdev/gitlab-data/backups] action create

    ================================================================================
    Error executing action `create` on resource 'directory[/gitlabdev/gitlab-data/backups]'

Then I found https://docs.gitlab.com/omnibus/common_installation_problems/README.html#reconfigure-fails-due-to-quot-39-root-39-cannot-chown-quot-with-nfs-root_squash which says I can disable storage directories management using manage_storage_directories['enable'] = false however even after setting that option I'm still getting the same error.
