Migrating to Nginx Gateway API from nginx ingress controller- concern on cookie session

Actually We are migrating from the NGINX Ingress Controller to NGINX Gateway Fabric (using Gateway API CRDs v1.4.1). Our goal is to replicate specific session persistence behavior for a production application currently installed gateway fabric version 2.4.1

1 can we achieve that by nginx open source version

2 ) is this feature is Is supported in the current stable release of NGINX Gateway Fabric

we were using these annotations on nginx ingress controller: nginx.ingress.kubernetes.io/affinity: cookie nginx.ingress.kubernetes.io/session-cookie-name: WebApp nginx.ingress.kubernetes.io/session-cookie-expires: 172800 nginx.ingress.kubernetes.io/session-cookie-max-age: 172800 nginx.ingress.kubernetes.io/ssl-redirect: “true”

can anyone help me on this
