In fact there is an example of doing exactly this in the manual: https://libguestfs.org/nbdfuse.1.html#Use-qemu-nbd-to-read-and-modify-a-qcow2-file https://gitlab.com/nbdkit/libnbd By the way I would be extremely wary of any tool which claims to process qcow2 files but is not using qemu code to do it. nbdfuse uses qemu-nbd (ie qemu code).
