That's a good question, its possible there's one or two options available, but its so niche that you might struggle finding one. There's not a lot of high performance USB4 only devices that aren't technically Thunderbolt, mostly looking for USB3.1/3.2 than USB4. Anything labeled USB3.x to 10GbE should work, it doesn't have to be USB4 since that's up to 40Gb/sec. There's USB3.x versions that support 10Gb/sec and 20Gb/sec, so 10GbE should function just fine through those. USB4 usually includes Thunderbolt, but not always. Its one of the defining differentiations for those of us with Thunderbolt eGPU enclosures. At least now a days, you can expect Thunderbolt and USB4 to be 40Gb/sec, which wasn't always the case.
I don’t think such a device is available since it would require more power than USB 3.x supports. There aren’t any 5GbE adapters that go beyond USB 3.x 5Gbit, which caps real-world speeds at around 3.6Gbit. I believe the market for this is very limited. The only 5Gbit adapter I’ve seen is still tied to USB 3.2 Gen 1, restricting it to 3.6Gbit in practice. It’s hard to find any of it for sale even in the UK—it’s a very specialized item.
A common issue is the lack of USB4 compatibility with Thunderbolt. This remains a point I pay attention to when reviewing specifications. It seems likely someone will develop a solution, but I believe most devices claiming USB3 support are actually TB3 and poorly advertised.
I just verified again and it looks like the Realtek RTL8157 5Gbit USB 3.2 Gen 2 adapters are available now, specifically the WP-UT5 model. I’m not sure if anyone else has created one besides that manufacturer, and I couldn’t find any for sale in the UK. It’s possible they’re developing a 10Gbit USB 3.2 Gen 2x2 version designed for fiber, but using it on a portable device wouldn’t make much sense since fiber isn’t meant to be frequently connected and could fail quickly. That’s where we stand.
