I didn't tested it but according to the site you can get from https://github.com/ventoy/backend/releases an image with *_casper-rw.dat.7z suffix (for Linux Mint) and extract the 7zip archive
Is Casper rw mint? I fought more distros used that label
casper seems to be for all ubuntu based distros, so including linux mint
