Following up on the previous update, if a workload (such as Planner) is enabled for Outlook by default, we don’t plan on hiding those groups from the GAL. The only other scenario currently under consideration where we would hide groups by default is “Secret Groups”. “Secret Groups” would be hidden from everywhere unless you are a member. “Secret groups” is on the Microsoft 365 Groups backlog, but there is no delivery date available at this time.

This is fast becoming a problem for us as well. As soon as we make a new group it is bombarded with requests to join from our students.
We need the ability to create groups private by default.
