I have found this link which seems to be getting me on the right track [1]

If I write disabled to the file
/sys/devices/pci0000:00/0000:00:1a.0/power/wakeup and then suspend the
keyboard no longer triggers a resume.  I got the device code by
unplugging and reinserting the keyboard and running dmesg.
Unfortunately when I power cycle it gets set back to enabled, so there
must be something writing to it at boot.  No idea what at the moment
