You can add a Raycast in the player's camera, and set its hit position as thw spawn point for your prefab. Here is an example:

 public float range;
 public GameObject prefab;
 public Transform playerCam;
 
 void Update(){
   RaycastHit hit;
   if(Input.GetKeyDown(keycode.E){
      if(Physics.Raycast(playerCam.position, playerCam.forward, out hit, range){
        if(hit.transform != null)
           Instantiate(prefab, hit.point, Quaternion.identity);
 
 }
 }
   
 }
