Deepstream without TensorRT

Is there anyway to use deepstream without TensorRT,I am using jetson nano,the issue is when using deepstream for my yolo model,I got very bad accuracy even my model is good when using without deepstream.So I think the issue is because of optimization the TensorRT did.So I wanna try deepstream without TensorRT.Thanks
