if you are refering to it hiding the serial than yes because it comes with exosphere but i dont recommend trying to go online well using this. this is typicaly meant for emmunand use, meaning you are running an emulated switch off of your sd card, if your system is banned then it does not matter but if you are not banned then be careful and if you run this behind stock mode do not install anything using installers like tinfoil or goldleaf and any other that can install nsp files as this will leave a trace on your system and get you banned. on emmunand it is set up to block communication to nintendo servers and you can do what you want on emmunand install what you want as it is offline to nintendo and is seperate from your system partition if you are asking does it change what nintendo can see as far as i am aware no it does not as the serial is built into the hardware i know that exosphere can blank your prodinfo but i dont think this will stop you from getting banned because the minute you go back into fullstock nintendo sees everything thats been done to the system partition as installing things leaves trace data in log files that as far as i know cannot be erased the only safe thing you can do is transfer gamesave data to and from the system partition but you have to make sure its not a modded save with certain games, one example is smash bros a modded smash bros save could get you banned however i have successfully used modded saves in pokemon scarlet marvel ultimate alliance 3 dragonball z kakarot and a few others a good rule of thumb is if the online is competitve and your modded save can give an advantage then dont inject it to the system partition because nintendo watches certain games for modded saves which could also get you banned so just be carefull what you do and have fun
