Question How to remove the transparent pixels that surrounds Shader Graph's default rectangle?

Try it yourself, Create a simple rectangle node in shader graph and you will notice some transparent edges all around it.

I'm making a pixel-style game and this effect seems so unmatched with the environment, Is there any way I can do to replace all these transparent pixels with a complete white color (1,1,1,1)?

I just want a basic rectangle, No transparency.

 

Did you try to add a floor or round function to the output? That should produce black and white image with no gradients.
