Nitrosense is a basic useless software and hardly has any settings other than fan speed, temp monitoring and power settings which is just windows power settings. It has nothing to do with your lcd settings. Overdrive can only be changed on your monitor but laptops typically have no way to change settings on them. Response times is not trustworthy at all and is mostly marketing nonsense to sell monitors. If you don't have ghosting, then it is fast enough.
Ghosting is something you see. If any movement has a trail behind it, that's ghosting. If you don't see it then it's good.
