From the lspci output should show the NPU but on the darp10 (Ultra 5 and 7) do not report this. I suspect that the other 14th Gen Models will also not list this.

Steps to reproduce

Boot Pop!_OS 22.04 (or any other Linux OS)
Run lspci and note that the NPU is missing:

Expected behavior

Something like this should appear in that output:

00:0b.0 Processing accelerators: Intel Corporation Meteor Lake NPU (rev 04)

Actual behavior

The output is missing

Device is disabled by default in coreboot. Needs an override to be enabled.

Is that by design or just how upstream has it?
