How to make this script only wall jump on certain walls?

void Start() {

 }
 public float GroundSpeed = 3f;
 public float GravityStrength = 5f;
 public float JumpSpeed = 10f;
 public float AerialSpeed = 2f;
 float verticalvelocity;
 public Transform CameraTransform;
 bool canJump = false;
 Vector3 Velocity;
 Vector3 groundedVelocity;
 Vector3 normal;
 bool onWall = false;
 bool CollidingWall = false;
 // Update is called once per frame


 void Update()
 {
     
     Vector3 myVector = Vector3.zero;
     Vector3 input = Vector3.zero;
     //Get input from the player
     input.x = Input.GetAxis("Horizontal");
     input.z = Input.GetAxis("Vertical");
     input = Vector3.ClampMagnitude(input, 1f);
     Quaternion inputRotation = Quaternion.LookRotation(Vector3.ProjectOnPlane(CameraTransform.forward, Vector3.up), Vector3.up);
    input = inputRotation * input;

     if (MyController.isGrounded)
     {
         myVector = input;
        
         myVector *= GroundSpeed;
     }

    
     else
     {
         myVector = groundedVelocity;
         myVector += input * AerialSpeed;
     }
     myVector = myVector * Time.deltaTime;
     myVector = Vector3.ClampMagnitude(myVector, GroundSpeed);
     verticalvelocity = verticalvelocity - GravityStrength * Time.deltaTime;
     if (Input.GetButtonDown("Jump"))
     {
         if (onWall)
         {
          
             Vector3 reflection = Vector3.Reflect(Velocity, normal);
             Vector3 projected = Vector3.ProjectOnPlane(reflection, Vector3.up);
             groundedVelocity = projected.normalized * GroundSpeed+normal*AerialSpeed;
         }
         if (canJump)
             verticalvelocity += JumpSpeed;
     }
     myVector.y = verticalvelocity * Time.deltaTime;
     //Use input to move the player
     CollisionFlags flags = MyController.Move(myVector);
     Velocity = myVector / Time.deltaTime;

     if ((flags & CollisionFlags.Below) != 0)
     {
         groundedVelocity = Vector3.ProjectOnPlane(Velocity, Vector3.up);
         verticalvelocity = -3f;
         canJump = true;
         onWall = false;
     }
     else if ((flags & CollisionFlags.Sides) != 0) {
         canJump = true;
         onWall = true;

     }
     else
     {
         canJump = false;
         onWall = false;
     }

 }

 void OnControllerColliderHit(ControllerColliderHit hit)
 { normal = hit.normal;

   
         }
 
 };

How would I make it so that this script only allows you to wall jump on certain walls? I've tried but I could find no solution.
