Bond0 as primary interface (Bonding, LACP)

RancherOS
1

I have an interesting problem, I can create a bond just fine. However if I just configure a bond0 and no other interface, the system tries to configure one of my bonding interfaces as a primary interface. I would like bond0 to be the primary interface. So in my example below eth3 is reconfigured as a regular interface. If I plug an additional network port at eth0 my bond0 works fine. Again if I only want bond0, eth3 gets reconfigure from bond slave to eth3 dhcp. Any thoughts?

rancher:
  network:
    interfaces:
      eth*:
        dhcp: false
      eth2:
        bond: bond0
      eth3:
        bond: bond0
      bond0:
        dhcp: true
        bond_opts:
          mode: 6
          miimon: 100
          lacp_rate: 1
          xmit_hash_policy: 1
        mtu: 9000
