So, I'm surprised to read this. On release day I tested our arm64
media locally using qemu/KVM VMs on an arm64 host here. I've just
booted the netinst media again now (debian-11.0.0-arm64-netinst.iso)
and I can see the following modules loaded, clearly including sr_mod:

# lsmod

I'm curious why you might be seeing different. Could you share more
details of your setup please?
