I write here what i plan to do on switch in next week. If i understound correctly.You don't need "un-hack", it could be dangerous if you don't know what are you doing.
if you want to backup your games you can use the NX-Dump Tool or DBI in MTP mode you can "copy" a installed game to your PC on NSP format.
read guides for understand what is to "Hack" a switch and you will understand what you need.
DO NOT FOLLOW ANY YOUTUBE VIDEO.
https://nh-server.github.io/switch-guide/
https://rentry.org/SwitchHackingIsEasy
are the best guides.
by the way ALWAYS START BY TAKING A SYSNAND BACKUP you need it in order to have a point to return in case you get a brick.
Backup game saves with jksv
Backup nsp with DBI
Remove all installed games and tinfoil to make room
Backup sysnad and Keys in hekate.
Format SD CARD and start from scratch with rentry guide.
Will be good? Its little complicated to almost unhack switch. Compare to ps Vita or old Nintendo 3ds. But i think i May done this
