Looking for aws cli efs to sync

I was expecting to find a command for syncing, similar to aws s3 sync... at https://docs.aws.amazon.com/cli/latest/reference/efs/ and https://awscli.amazonaws.com/v2/documentation/api/latest/reference/efs/index.html

I need to sync with an EFS instance in these ways:

1. Make the EFS contents identical to my local folder, including deleting items not present locally. This is for dev/testing use.
2. Or, only add items that are missing in EFS. Do not replace or delete any. This is for production use.

I'm not trying to sync to/from s3 nor do I want syncs to happen automatically, so DataSync isn't relevant. https://docs.aws.amazon.com/efs/latest/ug/transfer-data-to-efs.html It seems there should be a cli option that's easier to use than Transfer Family.
