How to shatter 2d objects without rigidbody?

Here is an example script that splits an object into pieces when hitting an object tagged "Bullet":

 using UnityEngine;
 
 public class ShatterGameObject : MonoBehaviour
 {
     public GameObject shatteredGameObject;
 
     private void OnTriggerEnter2D(Collider2D collision)
     {
         if (collision.CompareTag("Bullet"))
             return;
 
         var shatteredObj = Instantiate(shatteredGameObject, transform.position, transform.rotation);
 
         var rigidbodies = shatteredObj.GetComponentsInChildren<Rigidbody2D>();
 
         foreach (Rigidbody2D rb2d in rigidbodies)
         {
             Vector2 force = rb2d.transform.position - collision.transform.position;
             rb2d.AddForce(force.normalized * 100);
         }
 
         Destroy(gameObject);
     }
 }

Making a simple scene I got the following result (GIF):
