I'm not sure I understand what you mean. Check the contents of the
registers 0xe4 0xe5 0x5b 0x58 0x53 0x95 0x94 of the PCI device 00:11.0
(using lspci -xxx)? If yes, see below.

Here's the full lspci:

I don't understand. Match what?

Yes, when changing the BIOS default of 1.5V to 1.6V I get this
superiotool diff:

 LDN 0x09 (GPIO 2, GPIO 3, GPIO 4, GPIO 5, SUSLED)
 idx 30 e0 e1 e2 e3 e4 e5 f0  f1 f2 f3 f4 f5 f6 f7
-val 09 de 01 00 03 b4 00 ff  ff ff 09 ff ff ff ff
+val 09 de 01 00 03 a4 00 ff  ff ff 09 ff ff ff ff
 def 00 ff 00 00 ff 00 00 ff  00 00 00 ff 00 00 00

So yes, it's indeed GPIO2 bit 4.
