Detecting serialization reload in editor

Is there a good way to detect that Unity is about to reload assets before the reload happens? In essence, to be notified when Unity is moving all of the Mono state into C++ and then back?

It is pretty easy to detect it has happened after the fact;

 [ExecuteInEditMode]
 class UnitySerializationDetector {
   [NonSerialized]
   private object obj;
 
   void Awake() {
     obj = new object();
   }
 
   void Update() {
     if (obj == null) {
       Debug.Log("Assets reloaded");
       obj = new object();
     }
   }
 }

but is there a way to do it before the serialization happens?

Thanks
