It is possible to pass-through disk devices or partitions directly by adding them to your compose file in this way:
```yaml
devices:
-/dev/sdb:/disk1
-/dev/sdc:/disk2
-/dev/sdc1:/disk2
```
Use `/disk1` if you want it to become your main drive (which will be formatted during installation), and use `/disk2` and higher to add them as secondary drives (which will stay untouched).
