shil@localhost:~/sonic-buildimage$ docker run -it multiarch/debian-debootstrap:arm64-bullseye bash
root@b2e2fea86e2d:/# cat /etc/os-release | grep VERSION_CODENAME | cut -d= -f2
root@b2e2fea86e2d:/# cat /etc/os-release

NAME="Debian GNU/Linux"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

How I did it
if DISTRO is NULL, find it in /etc/apt/sources.list

root@b2e2fea86e2d:/# cat /etc/apt/sources.list | grep deb.debian.org | awk '{print $3}'
bullseye
root@b2e2fea86e2d:/# cat /etc/apt/sources.list
deb http://deb.debian.org/debian bullseye main
root@b2e2fea86e2d:/#
