Help with completely removing shine on materials

[Katastorm]

I don’t know if it can help you, but i found that

Remove Specular Highlights and Reflections from custom shader

On my side changing this line roughness = max(roughness, 0.002); to this roughness = max(roughness, 0); in the file 2021.3.34f1\Editor\Data\CGIncludes\UnityStandardBRDF.cginc and use Smoothness = 1 and Metallic = 0 on the material solve the unwanted shine issue.
