Samsung tab s8 plus connection via USB C-HDMI TO TV

Hello everyone. I have a question regarding connection of my tablet to my TV set. The question is : is there any way to switch off tablet screen while connected to TV? Mainly to save battery, the only solution I have found is that I can dim my tablet screen without affecting TV screen which also save the battery.
