is it possible to dynamically enable/disable this feature?

[rimzzlabs]

based on on .env variable, I want to turn off other language if its deployed for global
like this one

const getLocale = (cluster) => {
  return () => {
    const defaultLocales = ["id", "en"];
    // we have 2 clusters: production, and production-id, however I don't want the `production` to have translation feature but keep english content
    if (cluster === "production") return ["en"];
    return defaultLocales;
  };
};

const locales = getLocale(process.env.NEXT_PUBLIC_CLUSTER);

export default {
  i18n: {locales: locales(), defaultLocale: locales()[0]},
  defaultNS: "common",
  react: {useSuspense: false},
  reloadOnPrerender: process.env.NODE_ENV !== "production", // DEVELOPMENT-ONLY, IMPORTANT!
};

yes, that should work
