Hi @ashraf133,

Thanks for writing in. The documentation page also notes this as expected behavior:

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/rds.html#RDS.Client.describe_db_instances

Note

This operation can also return information for Amazon Neptune DB instances and Amazon DocumentDB instances.

You can read more about it here how to mitigate it using filters (this would be via the Filters parameter in boto3):
