Feature file vs Data binding


I am using feature file in Katalon where I have the description of my test in Gherkin.
My purpose is to avoid using Examples tables (+Scenario outline) for data in order to get them from external data base.

In my test case, I only have command line calling my feature file. All my variables are defined in the groovy test step.
So I have no variable defined in my test case
Is there a way to bind my variables (in the groovy) with my external data while managing the test execution?
