No, VNXe does not expose any bandwidth throttling, so replication will eat up whatever bandwidth is available over the network.
With Celerra Replicator v2 and VNX Replicator you are able to set replication throttles on each replication job based on time of day and bandwidth available.  The only thing that seems to be available with VNXe in Unisphere is a slide bar to set the RPO time.  What if you need to have replication use less bandwidth on during business hours and let it use more after hours and one weekends?  It seems that by setting the RPO slider to a specific setting really just has the VNXe source system hold all changes until the next interval then try to send them all over in bulk.  For example if you set the RPO to 4 hours a job will only run every 4 hours to send updates to the target VNXe.  Is there a CLI option to set this differently?
Does VNXe replicator have any option to throttle replication traffic based on 
time of day
