When Nirvana is fully attained, does consciousness or awareness completely cease to exist in every possible form?

I’ve been trying to understand what happens to consciousness or awareness when someone fully attains Nirvana. From what I gather, Nirvana is described as the end of suffering and the cessation of the cycle of rebirth. But I’m unclear on whether this also means that all forms of consciousness or awareness whether in a physical body or any other 'purified' or 'disembodied' form come to a complete end. Is it correct to say that after Nirvana, there is no remaining experience, presence, or awareness in any sense? Or is this question itself based on a misunderstanding of what Nirvana actually is?
