I'm not sure what you mean by "all packages". Surely you're not going
to download the entire Debian repository just to pick up the man pages
when they're already available on the web. Many in your collection
would seem destined to languish for ever (or until Debian moves on a
suite) without ever being consulted.
It would seem more efficient to process the man pages for the packages
already installed on the system, and provide your local copies through
a wrapper that notifies you of any that need providing as and when
they are demanded.

There's nothing more to a .deb file than two .tar.xz archives
inside an .ar archive, viz:

That's a bullseye for iwd being inspected on a buster machine.
No need to install anything or run specifically "Debian" commands.
Cheers,
