The best solution is probably to have your application hide the notifications since it already contains notification code. Run something like ExecWait '"$InstDir\\MyApp.exe" /uninstall' at the start of your uninstaller.

It might be possible to use one of the IToast* interfaces with the System plugin but there is a lot of code needed and I don't know if Windows let's you pretend to be another application by using its Application Model Id. For example, MSDN has this to say about IToastNotificationHistory::Remove:

The app ID of the app that sent the specified toast notification. This app must be part of the same app package as the app making this remove request.

MSDN also has this to say about desktop apps:

Generally, sending a toast notification from a desktop app is the same as sending it from a Windows Store app. However, you should be aware of these differences and requirements:

• For a desktop app to display a toast, the app must have a shortcut on the Start screen.
• The shortcut must have an AppUserModelID.
• Desktop apps cannot schedule a toast.
