How do I render a Quarto book more quickly?

Description

When rendering a Quarto book, is there a way to update only the HTML files of the chapters whose source changed, even if that might lead to some outdated content elsewhere (cross-references, table of contents)? A quick partial render?

I first thought I was looking for caching/freezing but that might not be the case. I'm dealing with a book that is nearly only text. I'm rendering three versions of it (languages) then linking them through babelquarto. The use case of quick partial renders would be a local preview (whereas the book would be fully rendered on CI).

Any pointer would be appreciated. 😸

Now reading the docs of preview, but I'm not sure it's what I'm after. 🤔

I've run into similar issues with websites (#3661) and the solution there is to use preview, since that can detect changed files and only render them, but I don't know how/if that works with (1) books and (2) multilanguage things like babelquarto :(

Thanks! Right, I fear preview wouldn't work well since I'm doing more than one render.

Is this for interactive writing? If you just Cmd + K to knit the current doc, it will only re-build the chapters that have changed.

Thanks! I'm slowly realizing my problem might be due to the exact setup of babelquarto, not Quarto (that solution works for the English version of my book 😸).
