Z-Wave frequency Samsung SmartThings HubV2

There is 3 different versions of the Samsung SmartThings HubV2

F-H-ETH-001 Early US Version
F-HUB-US-2 Late US Version
F-HUB-UK-V2 UK Version

Does anyone know if the US Versions are locked to Z-Wave on 908.42Mhz and if the UK version is locked to Z-Wave on 868.42Mhz which is the EU standard?
Can I change this in the setup?

No you can’t change it, it’s baked into the hardware.
