How can I switch between two cameras after a rotation of an object has finished?

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

public class AnimationPlay : MonoBehaviour
{
    public GameObject head;
    public GameObject[] cameras;

    private Animator anim;
    private bool started = true;
    private float animationLenth;
    private bool rotateHead = false;

    // Start is called before the first frame update
    void Start()
    {
        anim = GetComponent<Animator>();
    }

    private void Update()
    {
        if(started == true)
        {
            anim.enabled = true;
            anim.Play("New State", 0, 0);
            animationLenth = anim.GetCurrentAnimatorStateInfo(0).length;
            StartCoroutine(AnimationEnded());
            started = false;
        }

        if (rotateHead == true)
        {
            cameras[0].SetActive(false);
            cameras[1].SetActive(true);
            anim.enabled = false;
            head.transform.localRotation = Quaternion.Lerp(head.transform.localRotation, Quaternion.Euler(head.transform.localRotation.x, head.transform.localRotation.y, 0f), 1.0f * Time.deltaTime);
        }
    }

    IEnumerator AnimationEnded()
    {
        yield return new WaitForSeconds(animationLenth);
        anim.enabled = false;
        rotateHead = true;
    }
}

The problem is in this part :

if (rotateHead == true)
            {
                cameras[0].SetActive(false);
                cameras[1].SetActive(true);
                anim.enabled = false;
                head.transform.localRotation = Quaternion.Lerp(head.transform.localRotation, Quaternion.Euler(head.transform.localRotation.x, head.transform.localRotation.y, 0f), 1.0f * Time.deltaTime);
            }

I'm making the cameras switching before the rotation even start, what I need is somehow to make the camera switching when the rotation is end. Not after the rotation start but when the rotation is end.

Since you know what rotation you want to finish at, you can change cameras once you have reached that rotation.

Create and initialize a variable outside of the Update method:

private bool isFinishedTurning = false;

Then check whether the turn is completed in your update method and change cameras if it is complete:

if (rotateHead == true) {
    Quaternion targetRotation = Quaternion.Euler(head.transform.localRotation.x, head.transform.localRotation.y, 0f);
    head.transform.localRotation = Quaternion.Lerp(head.transform.localRotation, targetRotation, 1.0f * Time.deltaTime);

    // Check whether the current localRotation is the same as the target rotation
    if (head.transform.localRotation == targetRotation) {
        isFinishedTurning = true;
    }
}

// If the rotation is complete, swap cameras and disable animation
if (isFinishedTurning == true) {
    cameras[0].SetActive(false);
    cameras[1].SetActive(true);
    anim.enabled = false;
    isFinishedTurning = false;
}
