HAproxy doing LB to a dhcp failover landscape

I would like to know if is possible to do the IP forward using like round-robin for 2 backends, but the service will be routed is dhcp, ports 67,68 , I guess they are udp ports …

I want to use dhcp agent relay to a 1 one ip-helper, and this VIP will perform the LB to both backends servers.

Thank you for you reply.
