That can be helpful only if surveillance cannot film the screen directly, and surveillance relies on the position of the fingers. Given modern 4k cameras it's unlikely the latter can be done but not the former.

You can also use a privacy screen protector. Or use the two factor fingerprint unlock, which requires both a fingerprint and a PIN to unlock. And that's only after first unlock, so you can still use a separate, strong passphrase for BFU state.
Sure, a privacy screen makes things a bit more difficult for surveillance, because the camera would need a line of sight at a low angle, but once the code is known, the attacker can force a fingerprint and input the code.
