FreeBSD-15.1-RELEASE-amd64-dvd1.iso Optional Packages nowhere to be found after installation

I recently reinstalled FreeBSD-15.1 to an all new machine from the dvd, and like
many others am trying to install a number of optional package sets which are
supposed to be included in the dvd1 distribution as non-automatically installed
"package-sets."

the pkg-query -e '%a = 0' %o

produces a list of various package-sets located.  Resulting in a list of the following"

base/FreeBSD-kernal-generic
base/FreeBSD-kernal-generic-dbg
(12 more      )   base/FreeBSD-***-generic
(similar lines )   base/FreeBSD-***-generic-dbg
and ending with
ports-mgmt/pkg

Further inquiry reveals no directories or files with these names.

The above pkg query was made after putting a revised copy of the
FreeBSD_install_cdrom.conf and and modifying the FreeBSD.conf
in /usr/local/etc/pkg/repos/ as Sir Dice suggested and then experi-
enced a number of failed installed package attempts, with all trying
to go online before trying to find the file.

I assumed that "pkg install fusefs-exfat" would not be a big deal.

Appreicate any help.
