Yes, I am aware Cellebrite specifically publishes their ability to (or lack theorof really) to access GrapheneOS devices, which is a bit of a unique honour.

A different set of security practices is required for sophisticated adverseries. For instance a duress pin that immediately restarts the device and disables the USB port or resets the secure element.

I had this more in mind as a defense against unsophisticated physical threat actors, the proverbial $5 wrench attacks, thugs, unsophisticated or informal law enforcement etc.
