Cinemachine untouchable zone

How to make untouchable zone when using cinemachine? Suppose I have a mobile game, and I do not want the zone where the buttons are located to move the camera.

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

public class GetInputAxisCinimachine : MonoBehaviour
{
    public float horizontalAimingSpeed = 6f;
    public float verticalAimingSpeed = 6f;

    public float TouchSensitivityX = 10f;
    public float TouchSensitivityY = 10f;
    

    // Start is called before the first frame update
    void Start()
    {
        CinemachineCore.GetInputAxis = HandleAxisInputDelegate;
    }

    float HandleAxisInputDelegate(string axisName)
    {

        float leftTochZone = Screen.width - Screen.width / 100 * 80;
        float rightTochZone = Screen.width - leftTochZone;


        if (Input.touchCount > 0)
        {
            if (axisName == "Mouse X")
            {
                if (Input.touches[0].position.x > leftTochZone && Input.touches[0].position.x < rightTochZone || Input.touches[0].position.y > Screen.height - Screen.height / 100 * 70)
                {
                    Debug.Log("Mouse X");
                    return Input.touches[0].deltaPosition.x / TouchSensitivityX;
                }
                    
            }


            if (axisName == "Mouse Y")
            {
                if (Input.touches[0].position.x > leftTochZone && Input.touches[0].position.x < rightTochZone || Input.touches[0].position.y > Screen.height - Screen.height / 100 * 70)
                {
                    Debug.Log("Mouse Y");
                    return Input.touches[0].deltaPosition.y / TouchSensitivityY;
                }
                   
            }
                
        }

        //return Input.GetAxis(axisName);
        return 0;

    }
}
