I tried both 20190707-disco and eoan, there is no change in behaviour. I think in my case this is to do with the treatment of the RAID flag in UEFI boot, when RAID is not actually set up.

Can confirm this is still an issue with the most recent version alternative-stable-20190420-disco. The workaround is to use legacy BIOS boot. Another is to swap to ACHI instead of RAID/IntelRST in the UEFI bios. Even if the drive is not configured as RAID this option makes the drive invisible with a normal UEFI boot. This is also true for the complete Ubuntu distro, not just clonezilla. The difference in raid support between them (dmraid vs mdraid) does not affect things.
