You understand so little about the topic, yet keep posting on a ten minute basis obviously without even reading the links that are provided to you, it is embarrassing
How about starting off with what kind of Switch you got? Is it even easily hackable, meaning with a jig and a payload? Or do you need to get a modchip soldered which will cost you north of 250$ including the hardware? If it's the latter there's a chance you might not do it anyway due to the immense cost.
OG unpatched Erista switches need a jig and a payload injected, period. No way around. I do that maybe two or three times a year, mainly when I update the console firmware or in the very rare case that it somehow crashes and cannot reboot to payload. In all other cases you can reboot without needing a jig or a freshly injected payload. It is zero hassle to just keep something like the rcmloader in your Switch carryon case for the rare occasion you might need a jig and a payload injector at hand.
It is zero problem to keep your legit part (=Sysnand) and your hacked part apart (=Emummc) from each other with very little risk of getting banned (as in: you need to actively fuck it up by booting into Sysnand on CFW and then running unsigned software there), but as you seem to show no interest in reading the guides, I am very sure people will soon stop trying to help you anyway. Good day
