How to exclude a script from an asset bundle?

I noticed that all scripts referenced by a script included in a bundle are also included in the bundle.

I have a helper class assetManagerAsync in the “scripts” folder that implements some functions upon assetManager using Promise. I want to use it in components included in an asset bundle, but I don’t want that helper class to be included as well.

This also applies to NPM packages, whose code is also included in the bundle.

Is there a way to prevent this?
