Passthrough HDD to Unraid VM

Hello; I am trying to passthrough 2x 4TB HDD to my unRaid VM array and at first I passed them through via the below command
qm set 100 -scsi1 /dev/disk/by-id/ata-WDC_WD40EFAX-68JH4N1_WD-WXC2D53NEK11

This passes the HDD over but in unRaid they show as 0QEMU_QEMU_HARDDISK and as a result the drives dont spin down - they just hold data.

The 2 drives are on a HBA Controller
udevadm info -q path -n /dev/sdb

udevadm info -q path -n /dev/sdc

I am not able to pass the entire HBA card over as I have a drive on there as well for a different VM

I am however able to remove these 2 drives from the HBA card and plug them onto the MB sata ports but this is what my ports look like on the MB

00:17.0 SATA controller [0106]: Intel Corporation Device [8086:7a62] (rev 11)
        DeviceName: SATA Controller
        Subsystem: ASUSTeK Computer Inc. Device [1043:8882]

udevadm info -q path -n /dev/sdd

udevadm info -q path -n /dev/sde

How can i truly pass these 2 drives over?
you can't.
same for all hypervisors.
Only pass whole hba allow real hdd access.
What if I remove the 2 drives from the HBA and plug them directly into the MB sata port? Is each sata port able to pass through?
