Create JPA predicates without .createCriteriaBuilder call?

I have a Hibernate Expression in my service layer, that I would like to migrate to a Predicate for CriteriaBuilder:

SimpleExpression criterionSupplier = Property.forName("supplierId").eq(supplierId);
SimpleExpression criterionRfq = Property.forName("rfqId").eq(rfqId);

Which would look like:

Predicate supplierPredicate = cb.equal(root.get("supplierId"), supplierId);
Predicate supplierPredicate = cb.equal(root.get("rfqId"), rfqId);

As this is the service layer, I do not have available a session here to create CriteriaBuilder/Root. Is it possible to create predicates without CriteriaBuilder or do I have to inject the Hibernate SessionFactory in my service class?
