It appears that your system doesn't have the StorageD3Enable _DSD on any of the
AHCI ports, it's only for NVME.  However we already have a force for this in
the kernel for your system since kernel 6.3-rc1.:

3 is the right value (medium with DPM enabled)

The disk supports the feature we need, DevSlp.

The controller does not support 'sds' or 'sadm'.
'sds' is DevSlp
'sadm' is aggressive DevSlp

The 'sds' is the important one, this is what allows the disk to transition to
DevSlp during suspend.

Does your BIOS have any settings for this?

Something else you can do if it makes your experimentation easier is to take a
live USB key of Ubuntu and boot off that with your SATA disk disconnected. 
This should let you test whether this feature works without the SATA disk.
