Rancher 2 change preferred public IP to private IP

We recently just set up our Rancher 2 on AWS with HA. Each node has a public IP and private IP from when we set them up with RKE. It appears that the nodes are all using the public IP between one another. I’m trying to lock down the security groups in AWS, but when I try to limit it to the private IPs only it kills our Rancher environment. Is there any way to change the Rancher nodes from preferring the public IPs to prefer the private IPs?
