Install grml-rescueboot
I just tried it. It may work with a grml CD ISO; I didn't try it. The
code builds the grub.cfg entry correctly, and that works. But grub
refused to boot the debian netinst image I provided.
Charles, isn't it the issue discussed in (I have not tried it though):

(testing) 5.1.3. Booting from Linux using GRUB
https://d-i.debian.org/manual/en.amd64/ch05s01.html#boot-initrd
To boot the installer from hard disk, you must first download and place
the needed files as described in Section 4.4, “Preparing Files for Hard
Disk Booting”. https://d-i.debian.org/manual/en.amd64/ch04s04.html
menuentry 'New Install' {
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
linux /boot/newinstall/vmlinuz
initrd /boot/newinstall/initrd.gz
}
https://d-i.debian.org/manual/en.amd64/ch04s04.html
you can download the hd-media/initrd.gz file and its kernel
hd-media/vmlinuz, as well as copy an installation image to the hard
drive (make sure the file is named ending in .iso). The installer can
then boot from the hard drive and install from the installation image,
without needing the network.
Taken into account current size of netinst, I see not point in avoiding
of iso-scan:
760M debian-bookworm-DI-rc1-amd64-netinst.iso
