XF 1.5 Maintenance mode. (Board disable)

Hello all,
Is it possible to work on the forums using the ACP. Whilst your forums (Board) deactivate? Please respond as soon as possible.
Many Thanks,

P.s. I don't know which version it is, But I need to add a prefix so sorry if it's the wrong version

Only administrators have access to the forum while that option is enabled, so yes if the users are administrators.
