How to configure webpack with multiple options on @vue/cli?

Question

webpack

I created a project via @vue/cli, as far as I know it is on the webpack collector (there is no config file in the project by default).
Running the project via npm run serve
How to set up some things?:
1) Disable hot reload in the browser - if I change something in the project, it refreshes the page in the browser itself, it's very annoying.
2) When I write styles in the vue component, it automatically adds all the prefixes, which then change directly in the browser is very inconvenient to disable several checkboxes instead of one to remove one property. How to remove this substitution if this is not a production, but just a local run serve assembly?
