Hi @Francesco Fusco ,
If you're a team owner, you can manage a team in Microsoft Teams, for example change the name of a team.
More information below:

Change team name, description, and privacy setting
Go to the team name and click More options ... > Edit team. From there, you can set the team name, description, and privacy settings.
For the Microsoft Teams permissions, see:
