Material doesn't have _Stencil property

Unity Engine

Im using shader graph, i create URP unlit shader and I make my shader so far so good

but I get a warning

Material doesn't have _Stencil property UnityEngine.Canvas:SendWillRenderCanvases ()

I do need to use the stencil ops, how can I modify the shader so that it implicitly adds the stencil ops?

I have found a raw code shader that solves my problem, but I wonder if this is possible to fix in shader graph?
