I am trying to find a card that supports dual or more M keys for NVMe.

I can find these that have them with the M and B keys together but am wondering if they make a dual or more with M keys. I have been looking but I cannot seem to find anything. I don't know if they even make anything like that or if it's possible. All I find seems to support the sata speed with it and I'm not looking for that. I have the available slots if I need to go with singles I guess but I was trying to avoid the headache.
