How to fetch value for User-Defined Criteria Lookup LOV

I am trying to create a user defined criteria based on a DFF created at the assignment level. It is a DBS Level field. The DFF works fine

We want to create eligibility profile for DBS Level field to exclude exempt value and for rest of values wants to trigger checklist tasks.

But in User defined criteria task, Lookup value is mandatory.

DFF Definiton-

Value set Defintion-

Any idea how to add something there?
