“100% open and auditable from the operating system to the cpu” is the main goal of the Betrusted project: https://betrusted.io/ https://betrusted.io/

  The 4G modem is exceedingly unlikely to be audittable. Something like srsUE is not welcome on many telcos networks and requires some decently beefy hardware to run.

  It's possible to modify it and add a 4G modem, but that would probably be third-party. The creators of the project suggest using your phone's hotspot if you need connectivity when not connected to Wi-fi (something I heard in interviews they gave).
