How to stop cancel notification once the workflow is approved/reject from others users

I have a workflow which is using role for send approval notification parallel to multiple user once any user is approving the rest of users are getting the email for cancel of notification as it is approved by other user. Here the requirement is user do not want to get email notification for cancel of notification.

How can I do this or if I do this it will be applicable for that particular workflow or for all kind of cancel notification.

Any help will be appreciated.

Thanks in advance
