dbt run params and dbt test params in single DbtTaskGroup

I have a single sql model and its corresponding tests. I am trying to integrate cosmos.
I could run the single sql model and its corresponding test within the DbtTaskGroup().
But the problem is I need to specify different args for sql model and for test. How can I achieve this in single DbtTaskGroup()? There is operator_args that I could use, but it supplies this args for test as well.
