The absolute safest bet is to perform a wipe.
This may be effective at preventing the government from accessing the data. But as we see, the law, including the 5th amendment, doesn’t protect from legal exposure to obstruction-type charges. Or lying to the cops type charges if you say you’ll unlock the phone, but then you actually wipe the phone.

GrapheneOS has a feature which automatically restarts the phone if it hasn’t been interacted with after some user-configurable delay. For example, you could configure the phone to automatically reboot if it hasn’t been used for an hour. This way, even if my phone is seized, that reboot timer is ticking. Once it reboots, the encryption on the phone is basically unbreakable.
