On IDRAC9 SecureErase is giving operation not supported error.

We have been trying to delete the physical disks using redfish API and able  to delete disks under Storage/RAID.Slot.3-1/Drives/ using below redfish api  

redfish/v1/Systems/System.Embedded.1/Storage/RAID.Slot.3-1/Drives/Disk.Bay.5:Enclosure.Internal.0-0:RAID.Slot.3-1/Actions/Drive.SecureErase

But when we are trying to delete the drives under Storage/AHCI.Integrated.1-1/Drives using below redfish api  

redfish/v1/Systems/System.Embedded.1/Storage/AHCI.Integrated.1-1/Drives/Disk.Direct.1-1:AHCI.Integrated.1-1/Actions/Drive.SecureErase

We are getting below error message:

"The operation cannot be completed either because the operation is not supported on the target device, or the RAIDType of \"MD Software RAID\" does not allow the operation.

Even the drive details say it is supported

Few disk details -->

"SystemEraseCapability":"CryptographicErasePD"

"CryptographicEraseCapable":"Capable"

"RAIDType":"Unknown","RaidStatus":"NonRAID"

Below is complete error

NOTE: If this is the expected behaviour then is there any other way to delete the Storage/AHCI.Integrated.1-1/Drives/Disk.Direct.1-1:AHCI.Integrated.1-1 using any other redfish erase api?
