To legitimately link a Nintendo account to the Switch, you have to update to the latest version, yes. If you do not want to update your Switch, you will have to use a homebrew application like linkalho to create a linked account.Right, im just want to use the switch for receiving save files of Pokemon sword / shield to use in checkpoint.
Also, if i do create a user on switch, will it ask me to upgrade to latest firmware in that case I'll lose my unpatched switch
Is there a reason you don't want to update to the latest version on your Switch? If it's RCM vulnerable, then you can update the Switch to the latest version supported by your CFW (Atmosphere supports 11.0.1, which is currently the latest system version). The only reason you definitely wouldn't want to update your Switch is if your Switch is ipatched and trapped on 4.1.0.
