You entered in a kind of analysis that I'm not able to do without the help of someone else more skilled than me. I've tried to add the preseed file even on the initrd file located on the live folder,but it didn't work. I don't know what to do further,but you gave me more material to post another question,this time more oriented to programming,so I know which is the right place to ask and what to ask.

No. This list here and debian-live are the best places to ask.
At least i know of no better ones.
If i were in your situation i would try to find out how the software
in the initrd is supposed to deal with preseed.cfg.
We already know how to get the uncompressed cpio archive "initrd".
Curiously i put it into some playground directory and do:
mkdir unpacked_initrd
cd unpacked_initrd
cpio -id <../initrd
fgrep -r preseed.cfg . | less
which yields various file paths. (I tried with the /d-i/initrd.gz of
debian-live-11.1.0-amd64-xfce.iso)
lib/debian-installer-startup.d/S30initrd-preseed looks interesting.
It calls preseed_location() in lib/preseed/preseed.sh with the URL
file:///preseed.cfg .
So i'd begin to study what it does and insert messages which tell at
run time what's going on. Then i'd pack it up again by (i guess):
find | cpio -H newc -o | gzip > new_initrd.gz
and put it into the new ISO.
In preseed.sh i see at the start:
logfile=/var/lib/preseed/log
I'd try to find out how to assess that file after the modified ISO has
booted. (Is the initrd ramdisk filesystem the same as the Live filesystem ?
Does the log get copied from one to the other ?)
But of course this is an open ended adventure with lots of wrong ways
to follow and lots of things to learn.
Also consider the mind set of those who possibly could help you:
Would it be fun for them, or at least interesting and bringing progress ?
A first step in their direction would be to show patience and appreciation
for the work which they do while you are waiting for them to show up.
Have a nice day :)
