Installing Ventoy on microSD with a Linux VM on ChromeOS

[SpiritAxolotl]

Heard from a friend to use Ventoy for storing multiple boots on one USB. My current goal is to install a flavor of Linux entirely on a shitty Chromebook (that I fully own and have root access to). My current issues:

1. I don't know if microSD is supported (despite regular SD being supported)
2. I don't know if Ventoy isn't able to format the card in a VM (I'm not too knowledgable on how shared files work on VMs)

The command I'm running is:
sh ~/ventoy-1.0.96/Ventoy2Disk.sh -I /mnt/chromeos/removable/boots
Where boots is the microSD, and the path IS valid because ls works on it.
If the answer is "microSD isn't supported" I'll get a normal USB stick tomorrow. If the answer is "use a second computer not running a VM to format the card" then I'll use a second computer to do so.
