Hi @Anonymous
There is currently no way to disable the call quality feedback pop-up on Microsoft Teams.
In this case, we recommend you that please vote for it in Teams UserVoice. . Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
