1) Change interface name for node:

2) Check that nailgun refresh the interface attributes:
[root@nailgun ~]# fuel2 node interfaces download -f json 1 && cat /root/node_1/interfaces.json | grep enp
Configuration of interfaces for node with id 1 was stored in /root/node_1/interfaces.json

        "name": "enp0s5",
        "name": "enp0s6",
        "name": "enp0s7",

3) Set interface name with '@'
root@bootstrap:~# ip link set enp0s4.0 name enp0s4.0@enp
root@bootstrap:~# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
