The answer is yes if you are wishing to grill your food items with the help of an ugly drum smoker. You should choose the direct grilling process. If you are not in a hurry, place the lid on the smoker but not completely as it will provide the food items with the recommended temperature.
In case you are looking forward to a quick session of grilling, what you need to do is to cover the smoker with the lid completely so that the smoker can reach the highest temperature. In short, you can perform the grilling session if you know the procedure.
