If HAOS on Yellow is booted for the first time with NVMe data disk present, it should be preferred over the empty eMMC data partition. This will ease reinstall of the system and migration from CM4 to CM5. All other data disks (e.g. if a USB drive is used for them) are still treated as before, requiring manual adoption using the Supervisor repair.
