Option to disable vendor chunks

[Grafikart]

In a recent update vite behaviour changed and vite is now creating a vendor chunk but in some case (for an app with only one entrypoint) we may want to get only one file.
Is it possible to add an option to disable it, or did I miss something ?

I looked at the code and this option is linked to other options :(

You can disable it by setting build.rollupOptions.output.manualChunks to undefined. User options will overwrite the default.

not work, @Grafikart did you find out ?

  build: {
    output: {
      manualChunks: undefined
    }
  }

works a-okay for me!
