As shown in the documentation CSS Modules creates a unique classname of the format [filename]\_[classname]\_\_[hash]

example:

<button class="Button_error_ax7yz">Error Button</button>

Now what I want to know is, will it always be like this or can we change it? For example, when I move my code to production, will this format remain like this?

Let's say I just want to change it to [hash:8], if it is possible.

It's not ejected Create React App Project. And there is not any config file.
