As the doc says " Lumberyard’s components have a simple lifecycle. When an entity is activated, it calls Activate() on all of its components. When the entity is deactivated, it calls Deactivate() on all of its components."
and "Note that a component can be activated and deactivated many times before it is deleted. "
But I can’t find a Deactivate/Activate Component Node script ? only a Destroy Component as below … 
Is the solution that consists to add a child entity with the component and then Activate/Deactivate this child Entity the only way/good way to do it ?
