ASUS B1400CEAE fails to resume from suspend to idle by default.  This was
bisected back to commit df4f9bc4fb9c ("nvme-pci: add support for ACPI
StorageD3Enable property") but this is a red herring to the problem.

Before this commit the system wasn't getting into deepest sleep state.
Presumably this commit is allowing entry into deepest sleep state as
advertised by firmware, but there are some other problems related to
the wakeup.

As it is confirmed the system works properly with S3, set the default for
this system to S3.
