Ventoy: Boot different ISO files from a USB stick

Seems kind of cool. I saw a video about it: https://www.youtube.com/watch?v=9QU1EjQ48H0

Basic idea is that you setup your USB flash drive with Ventoy. At that point you can copy multiple ISO images onto the flash drive. Then when you boot the flash drive you can choose which ISO image to boot from.

So you could have Ubuntu_18.04, Fedora 32, Ubuntu_20.04 etc.. on the flash drive and then choose which one you want to boot. I'm interested to see if I can use it for firmware updates of components.
