Override filter = "clean-traffic" on per VM template basis

I wonder how one can override filter=clean-traffic to disable IP spoofing for certain my VMs. I am using OpenNebula 5.12.0.4. VN_MAD is set to “bridge” and BRIDGE_TYPE=“linux”.

FILTER=“” as below didn’t work (filterref=clean-traffic persists in resulting xml ):

NIC=[
  FILTER="",
  NETWORK="private",
  NETWORK_UNAME="oneadmin" ]

FILTER=" " as below didn’t work either (VM failed to be created with the error message “[Z0][VMM][I]: error: internal error: referenced filter ’ ’ is missing” ):

NIC=[
  FILTER=" ",
  NETWORK="private",
  NETWORK_UNAME="oneadmin" ]
