group_by parameter in frappe.db.get_list() function does not support grouping by multiple fields directly.

To achieve grouping by multiple fields, you would typically have to resort to post-processing the results of your query in Python. You would retrieve the data without grouping and then use Python to group the results based on multiple fields.
