The kickstart files from /ks/ are directly available on the ISO itself.
These are used during the installation and the only real difference
between the various kickstart files in the /ks directory of the ISO is
how they do the partitioning of the disk(s).

The ISO itself is built on CentOS 7.8 via Pungi:

[root at hephaistos ~]# cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

[root at hephaistos ~]# rpm -q pungi
pungi-3.12-3.el7.1.noarch

The Kickstart file used to *build* the ISO via Pungi is called 5209R.ks
(not included on the ISO) and looks like this:

[root at hephaistos kickstart]# cat 5209r.ks

The commands to build an ISO tree via Pungi that I use is this:

#> pungi --name=BlueOnyx --ver=5209R --destdir=/home/pungi/ --nosource
--nodebuginfo -G -C -B --bugurl=http://www.blueonyx.it --isfinal
--config=/home/build_cd.5209R/kickstart/5209r.ks --cachedir=/var/tmp/

#> /usr/bin/mkisofs -v -U -J -R -T -m repoview -m boot.iso -b
isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size
4 -boot-info-table -eltorito-alt-boot -e images/efiboot.img
-no-emul-boot -V BlueOnyx-5209R-x86_64 -o
/home/build_cd.5209R/BlueOnyx-$VER.iso /home/build_cd.5209R/5209R

#> /usr/bin/isohybrid -u /home/build_cd.5209R/BlueOnyx-$VER.iso

The only catch for using the above 5209R.ks is this:

It uses a local repository in
/var/localrepo/pub/BlueOnyx/5200R/el7/blueonyx/x86_64 to install the
latest version of the RPM "blueonyx-cd-installer". As the OpenVZ OS
templates and the YUM installer method don't need or use the
"blueonyx-cd-installer" I only have it in a local repository which is
used for the ISO-building.

The RPM for that is of course included on the ISO, so you should be able
to work around that if you want to attempt a full rebuild of the ISO
yourself.

Other than that: If you let me know what changes you want to make to the
ISO, then I might be able to assist you or can include these changes on
the next official rebuild of the ISO.
