Prevent changes in ScriptableObject type Asset in Editor. Dont save it.

Hi. I have a class like:

 [CreateAssetMenu(menuName = "Items/Item")]
 public class Item : ScriptableObject
 {
      public int Id;        
      public string Name;
 }

And create assets of ist type by CreateAssetMenu. The problem is: any changes in asset example ALLWAYS save. Doesn't matter press "Save" or "Don't save" when exit the editor. Changes in asset file allways save. I understand its might be how Unity asset database works, but its realy annoying some times. Is there any way to control this behavior and save changes only when its needs?
