Disable the GUI when the character moving

Hai everyone, i already make the player character to move to it is destination (animate the character to move to that destination), i wanted to disable the GUI button when the player character is moving, but i can't get it and work it out. Could you guys help me?

Here is the code:

 public class UserPlayer : Player 
 {
     public override void TurnUpdate()
     {
         //Moving animation
         if (positionQueue.Count > 0) 
         {
                     GUI.enabled = false; // This is the one that i want when the character still moving (animation still moving), disabled the GUI. But i can't get it
             transform.position += (positionQueue[0] - transform.position).normalized * moveSpeed * Time.deltaTime;
             
             if (Vector3.Distance(positionQueue[0], transform.position) <= 0.1f) 
             {
                 transform.position = positionQueue[0];
                 positionQueue.RemoveAt(0);
 
                 if (positionQueue.Count == 0) 
                 {
                     actionPoints--;
                 }
             }
         }
         
         base.TurnUpdate();
     }
     
     public override void TurnOnGUI() 
     {
         base.TurnOnGUI();
     }
 }

 public class Player : MonoBehaviour 
 {
 //movement animation
     public List<Vector3> positionQueue = new List<Vector3>();

 public virtual void TurnUpdate()
     {
         if (actionPoints <= 0) 
         {
             actionPoints = 2;
             magicAttacking = false;
             moving = false;
             attacking = false;            
             GameManager.instance.NextTurn();
         }
     }

      public virtual void TurnOnGUI()
       {
         if (GameManager.instance.currentPlayerIndex == 0 || GameManager.instance.currentPlayerIndex == 2)
         {
             //ToolTip Text
     move = GUI.Button(buttonRect, new GUIContent("Move", "Move the Player"));
     GUI.Label(tooltipRect, GUI.tooltip, label1);

     GUI.tooltip = null;

     //Move Button
     if (move)
     {
         if (!moving)
         {
             GameManager.instance.RemoveTileHighlights();
             moving = true;
             attacking = false;
             GameManager.instance.HighlightTilesAt(gridPosition, Color.blue, movementPerActionPoint);
         }

         else
         {
             moving = false;
             attacking = false;
             GameManager.instance.RemoveTileHighlights();
         }
     }
         }

Thank you
