Is there a way to Make a Team Invisible in the Top Right Corner?

I am currently making a team-based game. I would like to make it so the team is not visible in the top right corner until someone is assigned to that that team. I was just wondering if there was a way to do this without scripting, as it would save some time.

there is no way to do this without scripting

You can not make an team "invisible" if you do use the teams function. Especially not without scripts.

Most people do it like this: If a person joins the team, then create the team. If there is nobody in the team, remove the team.

I would recommend to try doing that.
