My company is deploying a new product using 3B+ Pis and I am looking for a way to updates the Pis going forward without re-imaging the SD cards every time. None of the equipment is connected to the internet so I can't use the normal update mechanisms. Is there a way to essential package up all of the updates into a single file so we can distribute a single update file to our customers? I know this process is done with Linux based firewalls but I can't figure our how they actually do it.
