Instantiate a little before the end of the raycast or on screen

I'm raycasting and instantiating an object at the end of the raycast I want this object to spawn slightly earlier in the raycast instead of at the far end of the raycast, how can I achieve that without increasing size of colliders etc?

Here is what I have so far:

         if (Input.GetMouseButtonDown(0))
         {
 
             Ray ray = camera.ScreenPointToRay(Input.mousePosition);
             RaycastHit hit;
             if (Physics.Raycast(ray, out hit, NormalMask))
             {
                 print("Mousepos" + Input.mousePosition);
                 target = hit.point;
                 print(hit.point);
                 Vector3 pz = target;
                 pz.y += 0.1f;
                 Instantiate(MouseClickIdentifier, pz, Quaternion.Euler(-90, 0, 0));
             }
 }

It would be more ideal if I can just instantiate a sprite on the 2d screen when I press with my mouse on the spot, basically I want a sprite to appear where I click on the screen, but doing it with raycasts puts it inside objects as in the sprite object it says to lookat the camera to make it look flat, the camera can rotate so it has to be dynamically done.
