I was able to tweak one of the download links and get it:
- Go to https://www.linuxmint.com/edition.php?id=322
- Copy the USA - kernel.org link
- Change https://mirrors.kernel.org/linuxmint/stable/22.2/linuxmint-22.2-cinnamon-64bit.iso to https://mirrors.kernel.org/linuxmint/stable/22.3/linuxmint-22.3-cinnamon-64bit.iso
- wget https://mirrors.kernel.org/linuxmint/stable/22.3/linuxmint-22.3-cinnamon-64bit.iso
