Office 365 Group - Email preferences

So we have Office 365 groups set up for our committees.  Staff needs to be able to add documents and calendar entries to the group, but they should not receive any emails.  I realize each user can shut this off, but as the admin I need the ability to stop email from going to the group owners.  This was easy with distribution lists, but that option doesn't seem to be there with O365 groups.  Can anyone help?  Thanks
