unity – How can I use one keycode key as toggle switch for two cameras?

using System;
using UnityEngine;
using UnityEngine.UI;
using Cinemachine;

public class CameraSwitch : MonoBehaviour
{
    public CinemachineVirtualCamera vcam;
    public CinemachineFreeLook fcam;
    
    private void Update()
    {
        if(Input.GetKeyDown(KeyCode.V))
        {
            fcam.enabled = false;
            vcam.enabled = true;
        }
    }
}

When pressing on the V key it’s switching between the cameras. I want that if I will press on the V key again it will switch between the two camera back fcam to be true and vcam to be false and so on each time pressing on the V key to switch between the cameras.
