disabling another objects sphere collider

Unity Engine
1

I want to disable another objects sphere collider.

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

public class APIJumpWirhGrav : MonoBehaviour
{
    private SphereCollider  OnTopOfPlayer;
  
void Start()
    {
        onTopOfPlayer = Player.GetComponent<SphereCollider>();
    }

    void Update()

    {

        if (Input.GetButtonDown("Fire1") && onTopOfPlayer == true)
        {
            ????????GetComponent<SphereCollider>().enabled = false;???????
        }       
      
    }
  
}

Drag a public reference to that “other object” into the script above and turn off its collider when you want.
