Disable overlay on boot

Just wondering what uci command I can use to safely umount overlay partition at boot completion. My intention is to boot ther device with build settings and allow configuration changes during operation but restore defaults on reboot. Thankyou

Non-persistent overlay?... what device? Are you comfortable using image builder? One way is to instantiate overlay in ram disk early in the init process...

Sorry not following. Can you please explain in further detail.
