Hi Martin,
One of my friend has a Aspire A715-71G laptop, it has the facility to install a NVMe M.2 SSD but HWiNFO64 doesn't recognise the port, is it because the laptop model is new? I am posting this as a feedback for you to have a look.
If there's no device plugged-in the PCIe port might be powered down and not appear in the list.
If the NVMe device is plugged in, it should appear under a PCIe port, but not as part of the SATA AHCI controller you listed.
