I believe the old White Wolf "Werewolf: The Apocalypse" RPG and its adventures/scenarios were their own unique 10-minutes-into-the-future animal, but one that skirted very close to the Cyberpunk genre in spirit - perhaps a sort of pre-Cyberpunk setting.
The D20 Call of Cthulhu was set more in the modern era than the near future, but I think any of the included scenarios could have been easy to adapt to cyberpunk, and the D20 system would have been easy to mix-and-match with any D20 Cyberpunk materials.
The BRP source book contains enough material for an inventive writer to build a BRP add-on for Call of Cthulhu; no scenarios.
As a 7th Edition Call of Cthulhu Kickstarter supporter, I (eventually) got a number of supporting materials for the 7th Edition game, including a PDF booklet of adaptations of Call of Cthulhu into other settings, including two future settings, one a sci-fi/horror setting, and the other a post-apocalyptic setting. Neither are quire full-blooded Cyberpunk settings by themselves, but could, perhaps, be adapted to one with minimal trouble. Both of these were fairly sketchy, and might not have included a full-blown setting, let alone a scenario.
The old BRP CoC End Time monograph works in a similar post-apocalyptic spirit. Again, not quite full-fledged Cyberpunk setting, but not too far off in spirit (remembering that films like Alien, Total Recall, and Outland took place in what was effectively a Cyberpunk setting might make it easier to make the leap from this space-based post-apocalyptic setting and Cyberpunk....)
I have a feeling a few classic CoC scenarios would be easy to convert into Cyberpunk scenarios. For example, take the ever-adaptable "The Haunting": a corporation hires investigators to "sanitize" a "legacy virtual reality asset acquired in a recent merger" for public consumption, one in which a handful of company engineers and hackers have disappeared, died, or gone mad; the virtual reality space might (as an expedient) resemble an old dark house in the woods, but could look like pretty much anything that you like (virtual reality being what it is). The investigators' research before entering the virtual world and what they find after entering it reveal that the eccentric developer, long vanished, had been delving into some sinister things while programming the virtual environment, and the investigators are not alone in there.... for any Keeper familiar with both Cyberpunk and Weird horror, the conversion would take little more than the re-writing of some fluff descriptions, and maybe a little time spent in adapting some character sheets....
