Full noatime in Silverblue/Kinoite

I want to have all of my mounts use noatime, but even after adding that option to everything in fstab (except my swap partition), findmnt still reports that some are using relatime:

  • /sysroot
  • /sysroot/ostree/deploy/fedora/var
  • /etc
  • /usr

How do I change these to noatime? They’re not listed in fstab.
