I want to disable a specific script of the children I don't want to disable the whole object

using System.Collections; using System.Collections.Generic; using UnityEngine; using System;

public class disableComponents : MonoBehaviour {

 public int selectedCharacter = 0;

 // Use this for initialization
 void Start () {
     selectCharacter();
 }
 
 // Update is called once per frame
 void Update () {
     int previousSelectedCharacter = selectedCharacter;

     if(Input.GetAxis("Mouse ScrollWheel") > 0f)
     {
         if (selectedCharacter >= transform.childCount - 1)
             selectedCharacter = 0;
         else
             selectedCharacter++;
     }
     if (Input.GetAxis("Mouse ScrollWheel") < 0f)
     {
         Debug.Log("--");
         if (selectedCharacter <= 0)
             selectedCharacter = transform.childCount-1;
         else
             selectedCharacter--;
     }
     if(previousSelectedCharacter != selectedCharacter)
     {
         selectCharacter();
     }
 }
 void selectCharacter()
 {
     int i = 0;
     foreach(Transform character in transform)
     {
         if (i == selectedCharacter)
             character.gameObject.SetActive(true);
         else
             character.gameObject.SetActive(false);
         i++;
     }
 }

}
