How to get rid of AWS CloudWatch SubscriptionFilters like DD_LOG_SUBSCRIPTION_FILTER_XYZ

[MarkusSintonen]

Describe what happened:
Our Lambdas all have CloudWatch SubscriptionFilters having names like DD_LOG_SUBSCRIPTION_FILTER_XYZ. We want to get rid of these as we are using Datadog Extension for getting the metrics (as recommended). These unnecessary SubscriptionFilters also cause issues with the very strict limit of 2 for SubscriptionFilters counts. This causes issues with pre existing SubscriptionFilters.

These DD_LOG_SUBSCRIPTION_FILTER_XYZ SubscriptionFilters seem to be coming from our AWS account level settings which have been configured via CloudFormation template from Datadog:

    new CfnStack(this, 'DatadogForwarderStack', {
      templateUrl: `https://datadog-cloudformation-template.s3.amazonaws.com/aws/forwarder/3.83.0.yaml`,
      parameters: {
        DdApiKey: 'USE_ARN',
        DdApiKeySecretArn: 'foobar',
        DdForwardLog: 'false', // We don't want to actually send logs to Datadog, just custom metrics
      },
    });

However we can not totally remove this as some of our Lambdas inside the account still use the legacy logs based metrics. But how do we omit certain Lambdas from getting polluted by these DD_LOG_SUBSCRIPTION_FILTER_XYZ?

Describe what you expected:
To be able to remove Datadog created SubscriptionFilters.
