So in case anyone else has the same question as me in the future here is the answer: I just got my Switch lite yesterday and "docked" mode of ReverseNX works like a charm.
I am very happy with my purchase, especially since it seems I struck gold...
Yeah I've found this post too. The thing is some people say it's possible, some say it's not. It doesn't help that I can't find a single video of a switch lite using ReverseNX let alone docked mode on it as opposed to quite a few of them...
