After failing at the boot loader step of the installation (which I've read your reply on another thread it's due to not being able to access the internet which makes sense), if I reboot, it doesn't load.
So what I did was follow the steps here https://help.ubuntu.com/community/Boot-Repair to automatically fix.
When I do this, I get back into same Debian GUI as during the installation process but of course, without the installer automatically popping up. It's booted from the NVME without the USB live key.
I've never seen the prompt for the snakeoil test login with 192.168.0.1.
The output of dmesg|grep -i e1000e is:
[ 1.239051] e1000e: Intel® PRO/1000 Network Driver - 3.2.6-k
[ 1.239186] e1000e: Copyright© 1999 - 2015 Intel Corporation.
Can't wait to get snakeoil going!!!!!!!

ifconfig -a doesn't show the eth, just lo and sit0.

Also, not sure if it helps, but when I run lshw -c NET, I get the follow unclaimed messages for both the network controller and ethernet controller

sudo modprobe e1000e comes up with some errors:

Can't sudo apt install any updates without internet which makes it tricky.
