How can we override core spr-cache.js

[tufail]

Please help me to load modified cache logic but not the core spr-cache.js from nextjs.

I need to modify the line : 121

if (data.pageData.pageProps.publish_date !== data.pageData.pageProps.updated_date)  // logic
    cache.set(pathname, Object.assign(Object.assign({}, data), { revalidateAfter: exports.calculateRevalidate(pathname) }));
  // TODO: This option needs to cease to exist unless it stops mutating the
  // `next build` output's manifest.
  if (sprOptions.flushToDisk) {
    try {
      if (data.pageData.pageProps.publish_date !== data.pageData.pageProps.updated_date) { //logic
        const seedPath = getSeedPath(pathname, "html");
        await mkdir(path_1.default.dirname(seedPath), { recursive: true });
        await writeFile(seedPath, data.html, "utf8");
        await writeFile(getSeedPath(pathname, "json"), JSON.stringify(data.pageData), "utf8");
      }
    } catch (error) {
      // failed to flush to disk
      console.warn("Failed to update prerender files for", pathname, error);
    }
  }

The logic is if date is not matching we don't want to write JSON file in cache.
