Attach static private ip address to NLB

i need to attach private-static ip to AWS-NLB via ingress controller helm chart

Im trying to attach static ip address to aws nlb via nginx annotations, but this doesn't work.

external:
  enabled: false

internal:
  enabled: true
  annotations: 
    service.beta.kubernetes.io/aws-load-balancer-scheme: "internal"
    service.beta.kubernetes.io/aws-load-balancer-subnets: subnet-####, subnet-####, subnet-####
    service.beta.kubernetes.io/aws-load-balancer-private-ipv4-addresses: 10.10.6.220, 10.10.16.220, 10.10.11.220

I try this with additional annotations:

service.beta.kubernetes.io/aws-load-balancer-scheme: "internal"
service.beta.kubernetes.io/aws-load-balancer-type: nlb
service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: "instance"

AWS Load Balancer Controller add-on installed to cluster

Please help me with this issue
