How to limit certain components from being used (imported) outside of their Nx lib?

Question

Imagine this typical Nx file structure represents my project. Is it possible to limit components from being referenced outside of their lib?

For example, I want the banner component to be available within the ui lib but not available for import in the data lib. There's a lot of "import bleeding" going on and I'm wondering if this can be limited and contained within their own lib?

In the libs/ui/src/index.ts file, you can specify what you want to export. Instead of the export * from './lib/banner/banner, choose what you want to export.
