ZTest Always for standard shader is not working?

I've downloaded the "builtin_shaders-2018.3.10f1.zip" from Unity download archive. On this page Render a object on top of another is written, that I must add "ZTest Always". On this page How to render some material over every thing else by alexi123454 wrote, that I must add it around line 60. It's not working. Here is the "Standard.shader". Where I must add "ZTest Always"?
