Unfortunately DynamoDB does not support predicate push down syntax, as its a NoSQL database and to apply the filter the entire table would need to be read regardless.
https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-etl-partitions.html
If this is a one-time read then you can consider the export to S3 capability but if you intend on reading continuously you may just want to read the table directly to get more up-to-date data.
There is for s3 tables but unfortunately not for DynamoDB.
What you can do is minimize the performance hit (and cost) by using the new s3 export for DynamoDB.
