Are you absolutely certain of this?

To use ACPI, you must have booted via EFI, as the only mechanism for
finding the ACPI tables is via EFI. If booted via EFI, the stub will
have created a stub DTB if there is no provided DTB, to pass the command
line and pointers to EFI data structures. This stub DTB should be
present in the usual place.

Thanks,
Mark.
