How to enable AWS Elastic Beanstalk health rule 'Ignore load balancer 4xx' through code?

Question

The latest AWS Elastic Beanstalk (EB) console has, under each environment health configuration, a new option to ignore load balancer 4xx errors:

This same option doesn't appear on the previous AWS console version, only on the latest.

I'm trying to enable this option through code, but I can't find any docs for it. I'm already enabling the "Ignore application 4xx" option through .ebextensions.

I already did this:

Went through the EB release notes to see if I missed the announcement. No luck.
Looked to the docs for the application 4xx feature, and it doesn't mention anything about a load balancer 4xx option.
Went to the EB public roadmap and found nothing there either.

Any idea on how to configure it by code? Maybe AWS forgot to hide that option on the latest console?

Request you to create an AWS ticket. I have worked enough with AWS to know that they might have missed releasing an SDK change for this. — Rajan Prasad, Mar 19 '20 at 21:25

I found the name of the configuration by:

Updating the configuration once from the AWS console for any environment.
Saving that configuration as an Elastic Beanstalk Saved Configuration.
Retrieving the just saved configuration with the EB CLI.

The configuration document I got back looks like this:

{
  "Rules": {
    "Environment": {
      "ELB": {
        "ELBRequests4xx": {
          "Enabled": false
        }
      },
      "Application": {
        "ApplicationRequests4xx": {
          "Enabled": false
        }
      }
    }
  }
}

I can now use this JSON as a ConfigDocument on my .ebextension .config file and it works!

I also documented the whole process here.
