AWS-Xray is not getting disable in Python

I have a XRAY_RECORDER dict in the setting.py file of Django. Where I have different settings for AWS Xrays like Daemon address, tracing name etc. In the same dict I also mentioned 'AWS_XRAY_SDK_ENABLED': False. In short, I want to disable AWS Xray SDK for my application. But it still sends traces in spite of setting it to False. Although I can turn it off using global_sdk_config.set_sdk_enabled(False) but due to requirements constraint, I have to enable or disable it via environment variables. But it still send traces in spite of setting to False.
