Add another main page to vue 2.6.6 project or inject a view without applying the styles imported in index.html

Question

I've a problem with a Vue-js application (Vue 2.6.6).

I need to create a new page in this application that must not be affected by vuetify and other styles placed in the head of index.html file. I wanna now if it is possible to inject a view (navigating to it with routing) without applying styles or if it is possible to create another entry point for the app, making it as a multi-page application.

I've found a documentation for doing it, but the structure of files and folders they talk about is different from mine (I did not create the project) and I don't understand what I gotta do to set multiple pages.

https://cli.vuejs.org/config/#pages

I have a "main-priv.js" file inside src, not a "main.js", don't know if it is same.

I'm really bad with configurations and stuff like that, I've probabily taken the wrong life choice with this work, but nevermind, can you help me?
