Can load balance in Kong using least-connections in db-less mode

My setup: I am using Kong in a DB less mode with KIC enabled. Kong chart version 2.6.4
Question: Can I load balance using least-connections option to upstream target in this configuration?

What i tried so far: I created a KongIngress and applied the annotation to the my upstream service. Kong admin API settings acknowledges that but I don’t see the desired result? My hunch is it is not working because each of my kong nodes are unaware of each other’s connections count and hence dont give desired result.
