Add Additional IPs to cPanel on Google Cloud Compute Engine

I created a virtual machine in the Cloud Compute Engine structure. I set up cPanel and everything starts. But the only problem is I want to add more than one IP address to the cPanel server. I can add a static new IP address via Cloud Compute Engine. But I don't know how to describe it to cPanel. there is a warning that cPanel has a Nat structure on it. Only one public IP address corresponds to the local IP address. There are no more. Please help me how I can do this.
