Object-level events on s3 buckets without new aws_cloudtrail

Hi! I know only one approach for enabling Object-level logging on S3 bucket via terraform - create new aws_cloudtrail and setup data_source , but in some moment it’s unusable(because we have only 5 trails per region and this limit we can’t increase )

So, what I can do in this situation? We didn’t have any other way for Object-level logging?
I will be glad to any help)
