Disable K8s ingress for certain projects

I configured K8s on my gitlab group , to deploy all projects under this group.
I installed ingress , I want to disable ingress for certain projects not all (back-end apps)
I couldn’t find anywhere the option to disable exposing these projects after deploying to K8s
I am looking for a CI/CD variable to disable ingress , or maybe exposing the service as (ClusterIP) instead of (LoadBalancer).
