You can't enable or disable AWS Cloud Trail as far I know?
You can enable the persistent storage of trails. But you can always access 90 days of events regardless of that being enabled

CloudTrail can be configured to save logs to S3 or CloudWatch Logs, but I think that even if you were to disable, delete, or tamper with these logs, you can still search and download unaltered logs directly from AWS using the CloudTrail Events page.
