Absolutely yes. You will have to power off your Switch to change the face plate.

Joycons will too, but they don’t have any impact on your hack.

Hacking actually does nothing to the Switch itself. Remove the SDCard and reboot, and (as long as you never ran CFW on Sysnand) nobody would be able to tell it was ever hacked. Think of Atmosphere as an enhancing layer on top of the Switch OS that allows it to do extra things. It never actually changes anything underneath. When playing Animal crossing the save is written to the Nand you are using. Here’s a discussion on Reddit that goes into more detail about transfers but while you read it, keep in mind how I started off this answer and you’ll be able to see that when you rehack your switch everything will still be where you left it.
Thank you for that. Will let you know the results of the surgery, doctor.
