How to setup nuxt config to compile scss not!globally?

Question

webpack

Good day.
In a certain layout, certain styles can be included in the head.
In the config I see only global styles.
But for the admin panel and the site itself, the styles are naturally different, and there is no longer enough imagination for class names.
I can’t find how to add the config so that the styles are simply compiled separately.
In theory, you need to register in build?
