'Can I reverse-proxy POST requests while using CloudFront CDN for GET requests?

Currently I have CloudFront distribution that serves SPA (spa.myapp.com) from S3 bucket. I have also web server deployed in k8s on AWS.

Is it possible to forward all POST spa.myapp.com/* requests to my web server instead? What components / configuration I need to do this?
Is it possible to forward all spa.myapp.com/api/* requests to my web server instead (regardless of http method)? What components / configuration I need to do this?

Generally I want to serve SPA from CDN but also have few endpoints server side on same domain.
