Is there a runtime check?
Well, basically both DMI and ACPI are completely different things, so I don't think it's right to check the availability of ACPI as a signal of the availability of DMI.
In theory they are only somewhat related, but in practice they're both part of a holistic system model - ACPI users complain if their system does not also provide DMI information.
