Willem here.
You would first need to get rid of the encryption before any of the tools
would be usable.
Exactly how you would go about making a daisy book with only some of the
content of the original one, depends on if you have daisy3 or daisy 2.2
books.
It boils down to unzipping the book and removing some entries from the
.opf and nav.xml files and then removing the relevant files from the
directory structure. This is for daisy3, for daysi2.2, it is the same
idea, but different files to be edited.

Good Morning,
I have a few Gigabytes worth of Daisy audiobooks, mostly magazines I
either copied from cartridges sent by NLS or downloaded from the BARD
website.
My digital media player(a Blaze ET) is authorized to play Daisy
audiobooks Encrypted with BARD's DRM, but it takes a really long time
to load ones with longer play times, and navigating within a long
Daisy program is a bit annoying.
Does anyone know a way of splitting a Daisy audiobook into a separate
audiobook for each top-level heading with little to no loss of audio
quality and retaining all lower level headings? Ideally, I'd like to
separate each Magazine into a separate Daisy folder for each article
and to be able to split any future novels I add to my Daisy collection
into one Daisy book per chapter, just as I merge my rips of CD audio
books into one flac file per chapter.
If the process can use the input Daisy book to automatically give the
separated parts a meaningful title/filename, all the better.
