ACPI? power-on/wake-up sleeping ethernet

I got a laptop which doesn't list ethernet, not even as PCI device in EFI shell. A research on the internet gave me hope - many people complaining about ethernet in deep sleep. Really I got the PXE boot option, three times out of hundreds. Once I was able to boot SystemRescue with ethernet working. I can't reproduce the steps, wake it up again, and turn off buggy power savings.

Is it possible to wake it up through ACPI? Inject and call it _ON? Please help.

Linux can "inject" the tables at runtime through configfs, acpi-call module was used to switch hyprid graphics.

Is one willing to look into the DSDT and able to implement?
