  According to https://docs.aws.amazon.com/cdk/latest/guide/cfn_layer.html paragraph 'Modifying the AWS CloudFormation Resource behind AWS Constructs'

        loadbalancer = aws_elasticloadbalancing.LoadBalancer(
            # params ommited
        )

        cfn_loadbalancer = loadbalancer.node.default_child
        cfn_loadbalancer.load_balancer_name = 'test'

this should change load balancer name to the value provided, but it does not do anything.
