Hm. Isn't that the size of a triple layer BR-R XL ("100 GB") ?


> How do I build just the first ISO of this size?

I cannot give advise how to let debian-cd produce a custom sized ISO.
But a few years ago i wrote a script which combines smaller Debian ISOs
into a big one. See
  https://wiki.debian.org/MergeDebianIsos

You could merge the first three BD-sized ISOs from
  https://cdimage.debian.org/debian-cd/current/amd64/jigdo-bd/
to get ~ 75 GB of result. Maybe even four of them will fit. You would
have to try how large the result becomes.

Or you could merge a larger number of DVD-sized ISOs from
  https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dvd/
to get nearer to the size limit of 93 GiB.


> Should I burn it with something besides K3B?

The burn program has not much stake in this issue. Use what suits you
best (and what can cope with the medium type).

The script  merge_debian_isos  offers to do the burning directly from
the submitted smaller ISOs. See
  https://wiki.debian.org/MergeDebianIsos#Merge_the_ISOs_directly_to_an_optical_medium

Given that you plan to use an expensive write-once medium, i advise to
first make a test run by
  https://wiki.debian.org/MergeDebianIsos#Merge_the_ISOs_to_a_single_image_file
or, if you have a large USB stick with disposable content, by
  https://wiki.debian.org/MergeDebianIsos#Merge_the_ISOs_directly_to_a_USB_stick_on_GNU.2FLinux


Have a nice day :)
