Move data disk back to original drive

I have Home Assistant running in virtual machine on my Synology NAS. A few months ago I used “move data disk” option to move data to an USB drive, but now, as I am moving all my VMs to SSD, I would like to move data disk back to main drive where HA is installed. How can I do so? Unfortunately there is no such option in HA settings.

Same for me: I moved from SD card to SSD and now want to move back, but there is no SD card to choose from!
