What you readily described has, as a matter of fact, applications in medicine in thr field of epylexia ande depression treatements, currently in the form of complex electrical apparatus linked to specific areas of the brain. It is however quite an impactful surgical operation, and it requires a diagnosis for a hard to treat series of symptoms that cannot be dealt with otherwise. It is not exactly that kind of stimulation, more like a "turn on - off" certain neural pathways via electrostimulation, but it is a thing.

would neuarlink do that?

I don't think so as it is mostly a general purpose interface that has its main purpose in human - implant (machine) interaction. But there is a way to stimulate a specific nerve in such a way that you can turn into the personification of horniness itself, I haven't heard of that in a while tho.
