webpack - exclude files from specific entry point

In my application I have multiple entry points. One entry point is creating a bundle which is restricted only for signed in users.

Is there a way to tell webpack to not bundle any file that needs to be restricted into the 'public' bundle? and instead not bundle it / throw a compilation error?

is there an exclude per entry point?

The only solution I can think of is creating two separate webpack config files, is there a better way?

Thanks

I will try to rephrase the question - Is there a way to enforce that some files will be excluded from a specific bundle/entry point, or in other words, there are files that I want in a specific bundle, and not in a any other bundle, and I want to enforce it.
