I solved it with this script:

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

public class SetFov : MonoBehaviour
{
    public float maxValue;
    public float currentValue; //Current value is the Min Value too
    public float smooth;
    bool isFoved;

    void Update()
    {
        if (Input.GetKey(KeyCode.E))
        {
            isFoved = true;    
        }
        else
        {
            if (Input.GetKeyUp(KeyCode.E))
            {
                isFoved = false;   
            }
        }

        if (isFoved)
        {
            GetComponent<Camera>().fieldOfView = Mathf.Lerp(GetComponent<Camera>().fieldOfView, maxValue, Time.deltaTime * smooth);
        }
        else
        {
            GetComponent<Camera>().fieldOfView = Mathf.Lerp(GetComponent<Camera>().fieldOfView, currentValue, Time.deltaTime * smooth);
        }
    }
}

Hey Dude Try This:

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

public class NewBehaviourScript : MonoBehaviour
{
    // Start is called before the first frame update
    float maxvalue = 4;
    float minvalue = 0;
    public float myvalue=0;
    void Start()
    {
        

       
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetButton( "Fire1" )) //change your button base on your need
        {
            myvalue+=Time.deltaTime;
               myvalue=Mathf.Clamp( myvalue , minvalue , maxvalue );
        }
        else
        {
            myvalue-=Time.deltaTime;
               myvalue=Mathf.Clamp( myvalue , minvalue , maxvalue );
        }
    }
}
