Any way to split clientBundle into smaller chunks?

My icons bundle size is 1008KB. Mostly because of using icons from the "flags" collection, which is quite heavy.

I don't know if it's feasible, but a way to automatically split the bundled icons into smaller chunk would be awesome. Example in nuxt.config.ts:

icon: {
    clientBundle: {
      icons: iconsToBundle,
      scan: false,
      sizeLimitKb: 1100,
      splitLimitKb: 500, // 500 by default
    }
  },

Start by tracing the clientBundle configuration shown in nuxt.config.ts and identify where the icons list is bundled. Determine whether automatic chunking can honor the proposed splitLimitKb while preserving the existing sizeLimitKb behavior. Done should include a documented configuration and a working example for the flags collection.
