How do I add a volume to an APFS file?
Select the Container on the disk where you want the Volume to be, and click on the + tool above, labelled Volume.

How to create an encrypted APFS volume from diskutil?

What’s the difference between APFS volumes and containers?
Unlike APFS Volumes, APFS Containers have fixed sizes which must be allocated when they’re created.
