The '--cdrom' is a valid option for many cases, but unfortunately not for all, since it doesn't allow the '-extra-args' argument - '-extra-args' only works in combination with '--location', not with '--cdrom'.

Btw. preseed is the non-interactive installation method based on d-i.
With the new subiquity installer the preseed successor is 'autoinstallation' - for more details let me refer to:
