ROM Hack Question Extract and inject save from a stock switch

[N0R7H]

Hi, I have a stock switch, and I'd like not to install cfw in it, so I'm wondering if there is a way to extract the save files to the pc, edit them, and then inject them again.

I read it, but don't know what tutorial are they talking about. I already have my switch on the latest firmware.

I'm not sure about the injecting part, I think in theory it should be possible.
But there's no guarantee it won't get your stock Switch banned.

I have dumped the NAND, and extracted the savefiles using HacDiskMount and the extract nand gamesave.rar from this thread. I checked the PLGP save file in PKHeX and works fine, but, after edit it, I don't know how to inject it again in my NAND.

When I used HacDiskMont, the saves were archives with just numbers, no extension, but after I extracted the savefiles from those archives with extract nand gamesave.rar, I had one folder for each archive, and a savedata.bin, which is the one I used on PKHeX. But I don't think I can put that bin file again in the NAND just like that, it must be another archive without extension, like the original, but I don't know how to repack the bin into that archive.
