question about modding v1 switch

[salazarcosplay]

I had a few questions about moddign the Switch

1 is the mod permanent?

2 do I have to re do everything if I turn off the switch

3 How do you mod the without modding the sysnand and only doing the emunand?

4 if the sysnand is not modded do I avoid getting banned

This guide would be a good start to get answers. The mod is permanent only if you install a modchip.
