doesn't make a difference:
nvme attach-ns /dev/nvme7 -c 6 -n 1
NVMe status: Controller List Invalid: The controller list provided 
contains invalid controller ids(0x211c)

this is a similar system also all drives connected directly to EPYC 
CPUs. This drive still has the default ns:

test220:~ # nvme id-ctrl /dev/nvme1

yes, I can create and delete namespaces, but I can not attach them:

test220:~ # nvme create-ns /dev/nvme7 -s 26214387 -c 26214387 -b 4096
create-ns: Success, created nsid:1
test220:~ # nvme attach-ns /dev/nvme7 -n 1 -c 0x6
NVMe status: Controller List Invalid: The controller list provided 
contains invalid controller ids(0x211c)
test220:~ # nvme delete-ns /dev/nvme7 -n 1
delete-ns: Success, deleted nsid:1
test220:~ #

no, just 4 lanes from CPU to NVMe Drive.

Hope this helps,
  Michael!
