Trust is always relative.
As for your question, it always comes down to threat profile, how well resourced your enemies are, and how much those enemies are willing to invest in attacking you specifically.
Say the CIA or NSA wants to target you. They may well break into your home and plant cameras such that they can see you type in your password. Then, once they have that, grab you off the street and take your phone.
For the vast, vast, vast majority of threat actors just disabling the USB-C ports data capabilities will stop them cold.
An entity like the NSA probably could image a locked down BFU GOS phone. How? No real idea. Would I be willing to bet against it? Nope.
The police or any more realistic hostile parties? Doubtful, they are more likely to just toss the hardware in a vault and forget about it until they get a viable attack.
Don't commit crimes. And if you are going to do things that a government getting access to years down the road is a serious concern then you probably should be factory resetting your device on a very regular basis.
