I'm reverse engineering the switch OS and I found code for a backdoor which allows you to load cart dumps from the SD card, you can't use it normally but it can be unlocked by writing a certain setting to a system save file. I think nintendo uses it for debugging. All it's needed is pegaswitch up to 3.0 or cfw on new versions.
Hint for anyone looking at the home menu: 0x5A3217.
Look out for leaks after cfw finally releases
