Hello SNI,
No, they have no logic to update themselves. They don't call home either. They just control the hardware.
I'd recommend you look at Windows Update.
The Lenovo Pro Dock has driver 8.5.3490 (8.5 M1) on Windows Update:

The driver became available as a normal update, but NOT critical, following Lenovo's request on 6th July.
Which version of Windows is this?
Kind regards,
Alban
