Helpful extension methods to customize Unity's shaders render state from script

ShaderRenderState.cs

public static class ShaderRenderState
{
    public enum ZWrite //couldn't find any similar enum in UnityEngine.Rendering
    {
        Off = 0,
        On = 1
    }

    public static void SetStencilRef(this Material mat, int value)                                      { mat.SetInt("_StencilRef", value); }
    public static void SetStencilComp(this Material mat, UnityEngine.Rendering.CompareFunction value)   { mat.SetInt("_StencilComp", (int)value); }
    public static void SetCull(this Material mat, UnityEngine.Rendering.CullMode value)                 { mat.SetInt("_Cull", (int)value); }
    public static void SetZWrite(this Material mat, ZWrite value)                                       { mat.SetInt("_ZWrite", (int)value); }
    public static void SetZTest(this Material mat, UnityEngine.Rendering.CompareFunction value)         { mat.SetInt("_ZTest", (int)value); }
}

/*
USAGE FROM SCRIPT:
    material.SetCull(UnityEngine.Rendering.CullMode.Back);
    material.SetZWrite(ShaderRenderState.ZWrite.Off);
    material.SetZTest(UnityEngine.Rendering.CompareFunction.Greater);

USAGE FROM SHADER:
    SubShader
    {        
        Cull[_Cull]
        ZWrite[_ZWrite]
        ZTest[_ZTest]
        // ...

        Pass
        {
            CGPROGRAM
            // ...
            ENDCG
        }
    }
