App Autoscaling module

Hello,

I have used terraform module “aws_appautoscaling_policy” to create autoscaling for ecs services. And the policy_type “TargetTrackingScaling” has created cloudwatch alarm automatically. So The question is, is there is a way to provide alternative values for the TargetTracking alarms which get created automatically?

resource “aws_appautoscaling_policy” “ecs_loadbalancer_scaleout_policy” {
name = var.lb_scale_out_policy_name
policy_type = “TargetTrackingScaling”
resource_id = aws_appautoscaling_target.target.resource_id
scalable_dimension = aws_appautoscaling_target.target.scalable_dimension
service_namespace = aws_appautoscaling_target.target.service_namespace

target_tracking_scaling_policy_configuration {
target_value = var.lb_target_value
scale_out_cooldown = 180
scale_in_cooldown = 300
disable_scale_in = false
predefined_metric_specification {
predefined_metric_type = “ALBRequestCountPerTarget”
resource_label = var.resource_label
}
}
}
