Resize disk0.img with macOS VM

Is there a way how to resize an existing disk (the primary one) of an macOS VM? It defaults to 64GB and thanks to APFS it occupies only the real size of data within (via _du -sh_ on the disk image) even though Finder reports 64GB (via _Get Info_ on the disk image).

This all works well with APFS "magic" 🪄 but if I want to backup the VM to an external non-APFS it will occupy all of the 64GB.

So the workaround I tried is to install macOS Monterey with the minimal disk size (24GB), but now I have only 2GB of free space left. Is there a way how I can resize the disk of an existing VM? I understand I could always create a new disk and attach it to the VM, but what about resizing the (primary) disk of the VM? Is that at all possible with macOS?
