I already know about these system settings. Other than a brute force approach to removing all messages from all applications on a system-wide level - it isn't the solution I'm looking for. It'd be easier to simply remove Parallels desktop rather than turn off every notification from every program that I use on my computer.
The article discusses 1) turning off ALL Apple notifications 2) Pausing all notifications 3) Do not disturb (similar to pausing) - again this is for all notifications 4) disabling Safari notifications (if you didn't notice I'm asking about Parallels Desktop - not Safari) 5) turning off application and system updates for my entire system/macOS.
I'm only interested in stopping messages/popups/notifications generated/originating from Parallels Desktop.
