Solution for Excessive EKS IP consumption

Hi, We're looking for a solution to remediate the excessive IP address consumption by EKS clusters. As the enterprise CIDR ranges are limited and tend to get eaten up fast by EKS we are facing an IP shortage and overlap.

We thought of having a peering between two VPCs (1 that is routable and the 2nd will be a non-routable VPC which is the by default AWS VPC). We would then have the IPs we would like to publish on the routable one...

Have anyone tried that approach ? Is there an alternative solution ?

Thanks in advance,
