I am running simple webserver on AWS

EC2 + RDS + ElastiCache + Cloudfront + Route53

All i am trying to achieve is to make my API backend work

but i see every month AWS charging me around 12-15$ for VpcEndPoint

I know that it is related to VPC and ipv4 Address, but is it possible to get my api backend working without it ( to save cost )?

I made major change in structure, tried to utilize ip6 but somehow i find VPC endpoints created in my AWS Dashboard, and i get charged for it
