How can I disable this collider, when two are present on the gameobject

I have a door game object. It has a box collider to make the player unable to pass through the door, and a sphere collider to sense the players presence and open the door. It has this script

 using UnityEngine;
 using System.Collections;
 
 public class DoorOpen : MonoBehaviour
 {
     private GameObject player;
 
     void Awake() 
     {
         player = GameObject.FindGameObjectWithTag("Player");
     }
 
     void OnTriggerEnter (Collider other)
     {
         if(other.gameObject == player)
         {
             transform.Rotate(0,90,0);
         }
     }
 }

I have found the possible solution of collider.enable = false; but i think this will create a problem since I have two colliders. If it helps, the sphere collider is marked as trigger, and the box collider is not. My question, how do I deactivate the sphere collider, without messing with the box collider?
