Cant find Standard Surface Shader (Instanced) in Unity

Been looking at doing GPU Instancing in the docs.

And as you can see from that first image, I should, in theory, be able to find the Standard Surface Shader (instanced) to my project. But when I open that same list in Unity, said shader is missing.
I’m running version 5.6.0f3 and this is the 5.6 version of the docs.

What am I missing?

Found it. There is a checkbox at the bottom of the standard shader to “Enable Instancing”

They should really update the documentation.

Here’s a picture of where the option is in 5.6 Standard Shader selected on a Material:
