Mail to group members

We have Office365 Groups for all our Teachers.

Groups example: Mathematichs, English, Phycics, and so on.

Different users in every Group

Every Group has also a Team created.

Common for all Teams is that the management staff is member of all Teams.

The management staff would like to send mail to group members (teachers)
But as they are Team members also, the will also get mails.

Can i somehow prevent the managememt staff from the mail group?
