is RPMB Fuse Set a factory state?

I bought a Galaxy Tab S6 and I'm going to verify if it is really brand-new. I personally haven't alter the device and the above picture is from this device's Download mode screen immediately after my purchase. It reads: - RPMB fuse Set - KG STATUS : PRENORMAL I have no idea whether

fuse Set

is a factory state. Is it? Concerning

STATUS

being

, I don't think this as a factory state (it seems the seller has already tried to flash an unofficial ROM or perhaps tried to flash back the official ROM from Android 10 to 9) Do you see any clue that could be used to prove that this device is not in factory state and not brand-new?
