Unbind Custom Event

Good Day.Im trying to unbind the custom event i created but when i type unbind in blueprint it only shows the default but not my custom event,why?How can i somehow else stop the event which i called?As that event is attached to inputs so based on camera view i have to change my input method(switch between them) so please give me a guid!:frowning:

Also looking for info about that

Using this to unbind a button URL. Have to unbind because the URL is set OnHover, and changing the button adds additional event instead of overwriting existing.
