ShadowCaster2D problems

Well, I’ve started a 2D project in Unity and I’m using URP to project lights.
On this player object, I’m using the shadows tool, but the sprite’s transparent pixels are emmiting unwanted shadows. How to solve this?

In the inspector settings for the shadow caster, you can manually set a custom shape.
