Animating the diffuse channel seperately of the alpha

Is it possible through scripting to animate the texture coordinates while keeping the alpha channel uv’s static? And how would one go about doing such if possible ?

In the built-in shaders, the diffuse and alpha are in the same texture, so it’s not possible to both animate and not animate a single texture.

So you’d have to use a custom shader for two separate textures for color and alpha, and then animate one. Something like this shader.
