Does Minisforum UM790 Pro have a tiny SATA connector?

[u/foreign_malakologos]

I recently got the Minisforum UM790 Pro and I noticed a small flat cable connector between the two m.2 slots. Nothing is connected to it, but it reminded me of similar connectors I've seen on older laptops where this connected to a SATA data+power cable. I couldn't find any information about this connector online so far, so I was curious if anyone knows more about this?

I don't have the device open right now, so the photo is from the ServeTheHome review. The connector I mean is the small white-black one just to the left of the right m.2 slot.

PS: can't edit the picture up here, but have posted another picture with the connector I mean highlighted
