If you have physical access, then you have total access.
Not if the storage is encrypted. That’s why vulnerabilities in operating systems/kernel are so impactful, as they can bypass that encryption.
Well no, if the device is powered off you need to brute force the encryption which will take a very long time.
However, if the device is booted you can just read from ram.
It’s a bit more nuanced even.
If you have one-time physical access, then you have total access, permitting the storage is not encrypted.
If you have recurring, undetected physical access, then you have total access.
Ex: Dropping a script into someone’s unencrypted /boot partition that captures the decryption credential, then coming back later to collect the credential and maybe also remove the evidence.
