This is actually misinformed, the discussion on the mailing list made it clear: there is NO full ACPI on these Windows ARM devices; they only use ACPI marginally and still require and provide device tree.
Phoronix should have revised that article, it's completely misleading.
One option would be to implement the custom non-standard Qualcomm drivers that technically it needs to implement anyway, but with support for the UEFI/ACPI interface.
On Windows, Qualcomm ships custom drivers that override normal ACPI platform logic in various places, IIRC
