Hey, i am trying to make something similar in my project, and i am struggling currently with the set-up have you considered making a tutorial on this project?
not yet, however, I have taken backup of my linux on a 64gb sd card, and nice thing is this that pc an be booted from this sd card. I can help you if you are facing issue, if you want someone can setup your pc. it can be done on vnc or remote desktop but for that you should have good internet connection and and freshly installed ubuntu-20.04.6lts so that there is no risk of putting the pc in someone's hands on the internet
