I can think of two ways to acheive this (each of which may be absurd given better knowledge of fs internals than I have): Either a per-process switch disabling atime updates or a way to obtain a read-only clone of a block device which can be mounted ro,noatime. Maybe fss is a way to go, but it's still marked experimental in 6.0 and taking the snapshot may outweigh the later performance gain.
