I would argue even hacking anything up to 7.0 is debatable since the vulnerability mentioned on the wiki page says it's probably not exploitable.Software exploits exist in firmwares up to and including fw 7.x

SciresM and every other big name Switch hacker who has contributed anything meaningful to the scene has already said that it's impossible to hack a firmware above 7.0. Not that it's unlikely or that it will take years but that it is 100% mathematically impossible to achieve it even if you understood the Switch's operating system perfectly. The only chance we have is if Nintendo releases a new firmware update and accidentally adds vulnerabilities to it (this did happen on firmware 3.0.0).
That said I do know a few hackers from other console scenes (PS4, PS Vita) who think that Scires is wrong, but Scires has thousands of hours reverse engineering the Switch's firmware that they don't have. Your best hope is that a cheaper and easier hard mod comes out. The Switch actually has several more hardware exploits but all of them are as complex and costly to pull off. That's probably the reason Nintendo hasn't bothered patching the BCT glitching exploit. They know if they do someone will just exploit a different flaw and their engineering time on fixing BCT glitching would be wasted.
The best/only way is a modchip for now if your Switch is patched. That being said the knockoff modchips are a total rip-off for the price they are asking. They are not even half the price in production and the design is stolen from the TX modchip.
