How can I optimize this Lerp movement in the Update Function?

I scripted a lerp animation in the Update function because my Coroutine code didn't work properly. So, in order to optimize it a bit, I tried using some guard clauses, but I don't even know if the logic is right. Is there a way to optimize it?

public GameObject[] GameMode; //end position

     public GameObject startPositionGameMode;     //start positions
     public GameObject[] finalPositionGameMode;
     
     public float speed = 0.5f;
     float current, target;

     [SerializeField] private AnimationCurve curve;

     public float radius=1;
     public Transform cube;

     public bool animationComplete =true;
 
     private void Update() {
         CheckState();
     }
 
     private void CheckState() {
         Vector3 distance = transform.position - cube.transform.position;
 
         if (distance.magnitude <= radius) {
             target = 1;
         }
         else {
             target = 0;
         }
 
         if (!animationComplete) return;
 
         animationComplete = false;
         Animate();
 
         Debug.LogWarning("CheckState" + animationComplete);
     }
 
     private void Animate() {
         Debug.LogWarning("Animate" + animationComplete);
 
         current = Mathf.MoveTowards(current, target, speed * Time.deltaTime);
 
         for (int i = 0; i < GameMode.Length; i++) {
            GameMode[i].transform.position = Vector3.Lerp(startPositionGameMode.transform.position, finalPositionGameMode[i].transform.position, curve.Evaluate(current));
         }
         animationComplete = true;
     }
