If you are not the rightful owner of this iPhone and do not possess the associated Apple ID and password, there is absolutely no way to gain access to the device. Apple’s security framework is designed to prevent unauthorized use, so the only circumstance in which you could unlock the phone is if the original owner willingly provides their credentials. In rare cases, access might become possible if the owner unintentionally removes the device from their Apple ID account, but this is purely accidental and not something you can rely on. In essence, without the Apple ID and password, the iPhone remains permanently tied to its legitimate owner.

I’ve been to those links and Apple did send me the link on how to remove it on the various devices but I didn’t understand and there aren’t any tutorials of it. I do remember the Apple ID and the password.
