Can be found in Settings > Apps > Sandboxed Google Play > Google Settings > System Services Updates

Anyone has seen this screen before?

I just noticed those new settings as well. For me, the "Automatically install system services updates" toggle is off and cannot be toggled on. Even with play services and play store installed.

    DSJ009 unfortunately I don't know. Maybe those updates are being handled through grapheneOS, so the google updates being forced off is expected? I can't say though.

      The toggle was off before that as well iirc. I suppose it is some kind of thing for privileged Play Services on Stock OS, as there it also does updating of some system components afaik.
      Probably no-op on GrapheneOS.
