Nibbana as Khandha-Vimutti

[Bakmoon]

I remember hearing somewhere that Nibbana is described as being "liberated from the aggregates" or Khandha-Vimutti, but I don't know where exactly that is said, and would like to be able to cite it. Is that in a Sutta, a Commentary, or somewhere else, and could someone cite the passage and possibly quote it for me please?

All that comes to mind is the kāyasakkhi (Body Witness). see MN70

unless you are thinking of the Parinibbana of an arahant who is then released from the Khandha fully, I am not sure, the search didn't render anything in the canon anyway that I could immediately see.
