Undervolting or overclocking

Hello everyone, I come here seeking your advice, I have a 4050 105w tgp, 16RAM, Ryzen 7435HS, 512gb ssd Lenovo LOQ gaming laptop, thing is this is my first gaming pc ever, I’ve heard a lot about undervolting and overclocking as such, should I screw with it, ps: max temp I’ve reached is literally 70c with ultra settings 80fps and 100% GPU usage at the moment so I assume the cooling system is good
