Excluding Entity from Spring JPA packagesToScan - spring

Question

Is there a way to exclude an Entity in a package using Spring's LocalContainerEntityManagerFactoryBean and Hibernate? I am using spring-data if that matters. I would like to manage the excluded entity with another datasource. I know that you can do it using hibernateSessionFactory (Ignore some classes while scanning PackagesToScan), but I would prefer to use jpa if possible.
Here's my config:
