The situation isn’t clear to me. The detailed explanation you provided is lengthy and technical. It seems the advice was overly verbose and included unnecessary details about PCIe lanes and motherboard compatibility. I tried to simplify the main points while keeping the core message intact.
The M.2 drives you're considering have a PCIe 3.0 x4 interface.
It shouldn’t affect them at all. I believe you’ll be fine—though I’m not completely confident. It seems adding a PCIe3 slot would make it work, and swapping the motherboard for a B450 wouldn’t change anything. The main concern is your graphics card isn’t fast enough to cause trouble. If the board only offers 8 lanes despite having an X16 connector, that might be an issue, but I don’t have any details. It probably isn’t common, as the holes only go halfway up, which seems rare and usually seen on lower-end cards. I’m not sure about my thoughts though.
