Change Bullets prefab as power

I am doing a 2d game and I want my player to be able to change bullets when he collides with an object(power) and destroy that object. I have a script and I was thinking that I need to implement 2 variables prefab ON/Off but now thinking much more I want to change with the help of a tag ( My player has in his script a public Rigidbody2D bullet) and this function void Fire() { if (photonView.IsMine) { var firedBullet = Instantiate(bullet, barrel.position, barrel.rotation); firedBullet.AddForce(barrel.up * bulletSpeed); } } this is the script that I was working on for switching bullets but I think it will not work to change a bullet that I add in the inspector for the Character script , to disable from this script and add other bullet . How I can make it by tag? using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class WeaponSwitching : MonoBehaviour
 {
     [SerializeField] private GameObject pickupEffect;
     public GameObject[] DisablePrefab;
     public GameObject[] EnablePrefab;
     public int selectBullet = 0;
     // Start is called before the first frame update
    
 
     // Update is called once per frame
     public void Bullet(Character bullet)
     {
         var effect = Instantiate(pickupEffect, transform.position, transform.rotation);
 
         foreach (GameObject disable in DisablePrefab)
         {
             disable.SetActive(false);
         }
         foreach (GameObject enable in EnablePrefab)
         {
             enable.SetActive(true);
         }
         Destroy(gameObject);
         Destroy(effect, 3.0f);
     }
   
 }
 

and I try this think with a BulletSwitch script to call the function from Weapon Switching script using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class BulletSwitch : MonoBehaviour
 {
 
     [SerializeField] private Character bullet;
     // Start is called before the first frame update
 
     private void Awake()
     {
         if (!bullet) bullet = GetComponent<Character>();
 
     }
 
     private void OnTriggerEnter2D(Collider2D other)
     {
         // or whatever tag your powerups have
         if (!other.CompareTag("Bullet"))
         {
             Debug.LogWarning($"Registered a collision but with wrong tag: {other.tag}", this);
             return;
         }
 
         var Bullet = other.GetComponent<WeaponSwitching>();
         if (!Bullet)
         {
             Debug.LogError($"Object {other.name} is tagged PowerUp but has no PowerUp component attached", this);
             return;
         }
 
         Debug.Log("Found powerup, pick it up!", this);
         Bullet.Bullet(bullet);
     }
 }

Using this after my player intercalates with that object with "Bullet" tag It doesn't appear any bullet anymore
