Qubes 4.0 is more flexible than earlier versions about placing different VMs on different disks.
For example, you can keep templates on one disk and AppVMs on another, without messy symlinks.
You can query qvm-pool to list available storage drivers.

Theses steps assume you have already created a separate Btrfs filesystem for your HDD, that it is encrypted with LUKS and it is mounted. It is recommended to use a subvolume as it enables compression and excess storage can be use for other things.
It is possible to use already available Btrfs storage if it is configured. In dom0, available Btrfs storage can be displayed using :
