Does My AlphaCool GPU Waterblock have ADD Gen 2?

Hello I want to know in a quick/easy way if my Alphacool Eisblock Aurora Plexi GPX-A AMD Radeon 5700 XT Sapphire Pulse/MSI Mech & Evoke has Addressable LEDs Generation 2 or Generation 1? I was modifying the motherboard settings, and I enabled Generation 2 mode and there was a lot of flickering happening. Does this mean the waterblock has Gen 1? Or perhaps I misconfigured it.

The only way for me to determin this right now would be to empty my liquid cooling loop, remove the video card, remove the LED strip and closely look for a serial number or model number. However this seems extremely unpractical. So far I suspect the block does not have "Gen 2 Addressable LEDs".
Can anybody confirm?
