I haven't ready any public writeups from emulator developers, no games have been released with it but Zelda BOtW2 is expected to have it. Some guesses are that it will be based on measuring specific call execution times.
The switch is already weak in terms of hardware so I am not sure how many games will end up integrating it. Regardless of what Denuvo says in marketing, it will slow down games. Nintendo has since tried to distance itself from it, but Denuvo has said they have entered NDA agreements with large publishers already. Denuvo would also need low level access and approval from Nintendo, so I am not sure why Nintendo is pretending to separate itself from this effort.
If Denuvo wants it to be effective, they need low level access from Nintendo. It's not possible for this to get approved to run on the switch without going through Nintendo. Depending on how effective this is, Nintendo would most likely be the first publisher to use it. Nintendo develops many of its most popular games in house. There was a lot of negative reactions to this so I imagine Nintendo wanted to distance itself from it publicly. It is the same company that took Game Genie, a game cheat cartridge for the NES, to court on the basis of "copyright infringement". Nintendo lost that case, but they have won recent cases taking down rom hosting sites.
