QUESTIONIs there a way to disable or restrict the Nintex Workflow/Forms apps from getting activated in Groups and Teams?
ANSWERCurrently SharePoint Online apps can be added to a Group site by any member that is within a Group site's Owners group. This level of permissions is also applied to the Nintex Workflow and Nintex Forms apps for Office 365.
There is a feature request for higher restrictions on the apps within the new Group Site site type here
, and if you would like to raise the visibility of that request to the product team, please add a vote to the request.
