Duration of SageMaker caching of multi-model endpoints

SageMaker offers a flag to indicate whether to cache models for a multi-model endpoint, that is enabled by default. https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_MultiModelConfig.html

For what duration does this get cached?

I tried searching "sagemaker cache duration" and "ModelCacheSetting" but did not find any hits. The use case is GDPR compliance and endpoint deletion and cleanup.
