Cannot create port with binding profile

There is no option to create port with binding profile in Horizon.
This is needed to create hardware offloaded ports, and it is possible via cli - https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/app-hardware-offload.html#creating-hardware-offloaded-ports

openstack port create --network private --vnic-type=direct \
