Global config options with AWS SDK 3

In the AWK SDK version 2 it was possible to set the global config options by doing something like:

   AWS.config.update({
    maxRetries: maxRetries,
    httpOptions: {
        timeout: requestTimeout,
        connectTimeout: connectTimeout
    }
});

Now the documentation says to configure it by service passing those options as an argument of an object like LambdaClient or EC2. But what if I use CDK and never use those client objects explicitly? Will a simple call of a constructor of such a client object change the configuration globally for all the subsequent usages the given type of resource or there is another mechanism to configure it?
