No, the kill switch is a literal electronic connection to the pin on the WiFi card that tells the firmware on that card to disable itself. ACPI may provide an alternative mechanism to trigger the same pin, but that doesn't mean ACPI can be modified to disable the physical switch. (What may actually be happening is that they switch is telling the embedded controller to toggle the WiFi card pin, in which case modifying the EC firmware might let you achieve the desired outcome, but that's still not an ACPI hack)
