Z490 TaiChi - Do you have a Block diagram of what lanes are shared among the PCIe slots, M.2 slots and the onboard/rear panel connectors.

I was scratching my head why the M2_3 slot was only PCIx 3x2. Then I saw that I need to disable the third party USB controllers, which the side effect is that is shuts of the USB C Gen3.2 2x2 port on the rear I/O panel and maybe other ports as well. I still have not tested all of them yet.
