Stop comment notifications for reviewers without Articulate ID

I decided not to use that functionality as team members expressed their concern about the bombardment of email notifications received. So instead, I export comments to a .csv file, save it as an excel file and use this to action and add my comments and to provide a copy to the reviewer once I've updated the relevant training materials, so that they know action has been taken. It's not perfect but it works for now until the 'notification comments' can be turned off.
