How to add condition in elbsg.config in ebextensions for elasticbeanstak

Currently, we use docker-compose and .ebextensions to update elastic load balancer security group. However now I have requirement to apply different security groups for different environment. How do I add the condition to elbsg.config ? Below is my current elbsg.config

option_settings:
 aws:elb:loadbalancer:
  ManagedSecurityGroup: "sg-xxxxxx"
  SecurityGroups: "sg-xxxxx"
 aws:elbv2:loadbalancer:
  ManagedSecurityGroup: "sg-x"xxxx
  SecurityGroups: "sg-xxxxx"

Wondering if the normal yaml condition would works or there is a separate syntax for elbsg.config to work ?
