Not really, because tools like Cellbrite are more limited with BFU, hence the manual informing LEO to keep (locked) devices charged, amd the countermeasures being iOS forcefully rebooting devices that have been locked for too long.
If you mean forcing an iOS device out of BFU, that's impossible. The device's storage is encrypted using a key derived from the user's passcode. That key is only available once the user has unlocked the device once, using their passcode.
