Wired streaming?

Great - it has a dongle.

But.

There are a few use-cases where it would be more convenient or required to be wired.

Is there any support for this?

For example, if you have more than one headset in use at the same time nearby. This might not be an issue with one, but with ten, or with a heavily used network on the same frequency, or if 6GHz is not legal in your jurisdiction it may be a problem.
