Test event triggers for certification testing

[PhLuReh]

I'm currently running through the PICS files for v1.4.1 and came to the mandatory DGGEN.S.A0008 (Indicates that node is configured for test event triggers.) - at least mandatory if General Diagnostics Cluster is implemented as a server, which is the fact as default in esp-matter. Here's the PICS:
General Diagnostics Cluster Test Plan.zip

Currently ./chip-tool generaldiagnostics read test-event-triggers-enabled 1 0 reads as TestEventTriggersEnabled: FALSE.

Is this already the correct and complete answer? I did not read nor run the test cases for this cluster, but I also could not find the correct answer for PIXIT.DGGEN.ENABLEKEY (EnableKey for TestEventTrigger Command is provided by the manufacturer). Where do we specify the key? Didn't find it either in menuconfig.

Or more generally, is there some information about PIXIT-predefines in esp-matter?
