Answer: Add AWS Global Accelerator in front of the ALB.
ALB does not support Elastic IPs directly and uses multiple IPs that can change. AWS Global Accelerator provides two static anycast IPs that front the ALB, providing static endpoints for customers while distributing traffic globally. This meets the requirement of max two static IPs without changing the ALB setup.
