The bullseye amd64 netinst iso does not include this particular package.
(Don't know why. I did not manage to understand the logic behind the
selection, which packages get included in the firmware-containing isos.)
So, installing it 'offline' from the netinst iso is not possible.
However, the new mechanism for firmware installation basically should have
detected the need for that firmware, and install it via your wired connection.
If you sent us the installation logs (compressed), we can try to find out, why
that did not work.
Another way for you to deal with this situation: if you have the required
ucode15.fw firmware file handy at installation time (for example from another
system), you can copy it to a removable storage (like a USB stick), and
plug it in, when asked for firmware. (I assume, you got a dialog saying that
such firmware file is missing, and if you have it available on a storage,
right? That's right at the beginning of the installation process.)
Of course, this is not the perfect solution for all users, but I have
prepared a stick here, where I have firmware for my wireless-LAN module
stored onto. For installation tests or the like...
