Hello,
When using Microsoft's website to generate ISOs, it is only able to generate ISOs for the latest version (26H2), which is the link that Rodrigo provided to you.
If you'd like an older version, your best bet is UUP Dump or the Internet Archive. Although both are third-party websites, UUP Dump uses a script that you download to get update files directly from Microsoft's servers. The Internet Archive, as you may know is more community-uploaded content, so it's hit or miss on whether you'll find what you need.
I hope this information helps.
