Can we change default group's permission?

In my company, each time a new user is added to Redash I need to remove newly added users from default group because default group has full access permissions.
So I’d like to toggle permission of default group using manage.py groups list command to prevent new user creating query. But is it no problem to change default group configuration? Our Redash is v8.0.0.

I wouldn’t modify the default group permissions. Every user is added to the default group automatically. It’s a “special” group in this way. It would be better to simply remove data source access from the default group and create new groups for more fine-grained control.
