How to change plotting options in deep learning networks?

I have trained a deep learning network, and the training progress graph appeared from trainNetwork function. This curve shows training accuracy, smoothed training accuracy, and validation accuracy. I need to remove smoothed training accuracy curve from the graph. Could you please help me? https://ch.mathworks.com/help/deeplearning/ref/trainingoptions.html?fbclid=IwAR0zK3F4pzPV_DqbAkRk_Ou7CmN3viJMXVx-ovnEmLfvc_M8dNWw3vZvMPs
