Clear and concise description of the problem

Vite now will not only insert preload directives to the HTML file by the build-html plugin, but also preload helpers for all non-HTML entries by the ImportAnalysis plugin.

And sometimes, you really want lazy loading rather than preloading everything, even for the main HTML entry. There should be a method to control the preload directives generation and preload helper insertion.

Suggested solution

A boolean switch in the config file is enough for me. But maybe a hook function will be better.
