No there isn't at the moment and there isn't anyone publicly working on an exploit. The only way to hack an OLED unit is with a modchip and that doesn't look like it'll be changing anytime soon.I have a Switch OLED and my old Switch v2.
Is there no way to hack the v2 like how you hack 3ds or Wii U? Like just put a file in your sd card or visit a website to hack the Switch?
