/home on a different drive

I'm not 100% sure I wanna stay on bazzite so I'm trying to install with the /var/home volume on a second drive so I can reuse it on another install. I keep getting a different error each time.

My question is: is it even possible to have /var/home on a different drive? Because if not, well there's my issue.

Solution

This is the partition scheme i used, pretty much as the manual partion guide says but with /var/home in a btrfs volume on another drive
