-     *
-     * <p>
-     * Background:
-     * AWS SDK for Java v2 uses the system property
-     * {@link SdkSystemSetting#AWS_REQUEST_CHECKSUM_CALCULATION} to determine
-     * whether request payloads should have a checksum calculated.
-     * <p>
-     * According to the official AWS discussion:
-     * https://github.com/aws/aws-sdk-java-v2/discussions/5802
-     * - Default SDK behavior may calculate checksums automatically if the property is not set.
-     * - Automatic calculation can affect performance or cause unexpected behavior for large requests.
-     * <p>
-     * This method ensures:
-     * 1. The property is set to "WHEN_REQUIRED" only if the user has not already set it.
-     * 2. User-specified settings are never overridden.
-     * 3. Aligns with AWS SDK recommended best practices.
