With 2023.6.1 how to move the data disk?

I have a RP in an Argon case which exposes a SSD to the RP. From HA->System->Hardware I can see /dev/sda installed and recognized. How do I interact with it to newfs (init it) for home assistant and get it mounted as part of the boot process? Right now ‘move data disk’ does not show the sda device.
