Replace cog with casette

is the Zwift Hub One just a normal Zwift Hub with the cog pre-installed? Can I replace the cog by a cassette just like I can replace the casette by the cog upgrade kit at the normal Zwift Hub?
If so, the Zwift Hub One could be reconfigured for other platforms that don’t support virtual shifting.
Any experience?

Yes it’s just a Hyperglide compatible freehub body with a single-cog cassette on it.
