Peter from Xiamen Carbon Speed (XMC), active on this forum, definitely has that spec. You can email him.
I recommend Pillar cx ray or the cheaper Pillar wing 20 (pillar wing 20, not some other pillar model) as spokes, and house hubs, or novatec.
Get full T800 rims, it's worth it (not much of a premium, but definitely worth it.
Get brass nipples instead of alu if you ride in corroding environments (salt, rain, mud, crap, winter, commuting...). They make wheels / spokes more serviceable.
Farsports will cost a bit more, but they're the goat of chinese OEM stuff. Email them, dont use the website. Pretty certain they have that spec as well.
I've bought from both and recommend both.
Lots of other options, ofc.
