No, stay in stretch.

1) Become root.

2) Mount buster installation in, say, /mnt.

3) Classic chroot sequence:

mount -o bind /proc /mnt/proc
mount -o bind /sys /mnt/sys
mount -o bind /dev /mnt/dev
chroot /mnt /bin/bash
# You're in chroot now
# Do not leave until instructed

4) Prevent buster services from running:

cat > /usr/sbin/policy-rc.d << EOF
echo All rc operations are disabled by policy: \$1 \$2
exit 101
EOF

chmod 754 /usr/sbin/policy-rc.d

5) Hard part starts here:

dpkg --configure -a
apt update
apt upgrade -s


6) Cleanup:

rm -f /usr/sbin/policy-rc.d
exit
# You left chroot

7) Finally:

umount -l /mnt/proc
umount -l /mnt/sys
umount -l /mnt/dev
umount -l /mnt
