Hi Basharat, 

We don’t have option to cancel the double click event, if you need to skip the event use separate conditions for your scenario. Still if you face any issues share us more details such as screenshot or video of your requirement.

Yes, I need to skip the default double-click event on annotation. It lets the user edit the annotation. I don't want to edit it on double click on the canvas. Is it possible?

Use AnnotationConstraints.ReadOnly constraints in diagram to prevent the user to edit the annotation by double click. Refer to the below mentioned documentation and sample.
