Afaik, UEFI (at least on ARM hardware I worked with) embeds the DeviceTree for non-ACPI boot usecases, so the user is no longer responsible for providing the proper DTB for that board, although the user can still override it if needed. Last time I worked with ARMv8, UEFI provided both ACPI tables and the embedded DTB, since ACPI support was undergoing a major rewrite in the kernel at that time.
