Make 0/1 columns cod_flag (from cod) and returned_flag (from returned), 1 meaning Yes. The inputs X are category, order_value, discount_pct, delivery_days, customer_orders and cod_flag, with category one-hot encoded by pd.get_dummies(..., columns=["category"], dtype=int). The answer y is returned_flag. Split with train_test_split (test_size=0.25, random_state=42, stratify=y).
For n_estimators in [5, 25, 100, 300] (random_state=0), store a dict from the number of trees to the test ROC-AUC, rounded to 3 decimals, in result.
