tracker-miner-fs-3 should not be started as part of the gnome-initial-setup process
Looking at this log from a recent GNOME OS test cycle:
tracker-miner-fs-3 started and failed as part of gnome-initial-setup. However, filesystem indexing is not needed during the initial machine setup.
Adding a ConditionUser line to the systemd service may be enough to solve this - see https://gitlab.gnome.org/GNOME/tracker-miners/-/blob/master/src/miners/fs/tracker-miner-fs.service.in?ref_type=heads#L3
