In the page template, I think you should be able to use the OnInit or OnLoad event handler or similar to set ContextMenu.IsMenuEnabled = false.

Sounded like that would do the trick but it didn't.

Inheriting from SimplePage doesn't do the trick?

This will solve your problem

protected override void OnPreInit(EventArgs)
{
    ContextMenu.IsMenuEnabled = false;
    base.OnPreInit(e);
}
