Way to clear option fed_admin_login['login_menu']

[adnoh]

Hello,
in the backend you can set the frontend login menu, but you can never clear this setting (exept of clearing the hole fed_admin_login option in tools).
It would be great to just unset that part of the config array fed_admin_login['login_menu'] on that page or in the tools
