Aurora R12, PCIe4?

Hello, this is my first post! I recently bought an Aurora R12 (11700KF (liquid cool), 3060 Ti, 32GB ram, 1TB NMVe PM9A1). I've been loving it, it runs all the games I've played flawlessly. I will keep it brief as I have a couple basic questions to start. 

I installed a second intake fan today so I got a chance to take a look inside and I noticed my PCIe slot under my GPU is labeled PCIe4. I was under the impression these motherboards only had PCIe3. Is this something new? 

Also, I noticed that in AWCC fusion tab, I don't have "advanced view" for my CPU or my RAM. Only my GPU has it. I called tech and they walked my through two AWCC reinstalls already. I've updated all the drivers. I don't know what else to do. The tech said my 11700KF is not able to be overclocked. Is that true? Anyhow, I was able to change to XMP1 in bios and now my RAM went from ~2300 to 3391 MHz. 

Thanks for any help
