You have to check with the manufacturer to ensure it works with the OS on the Bootcamp partition.
There is no Bootcamp “compatible” hardware because Bootcamp isn’t an operating system, it’s functionality built into your Mac.
So, you have to check to see if the dock, displays, and any other ancillary devices are compatible with macOS and Windows 10 (for example).
That said, docks and displays rarely have specific OS drivers. Get quality ones of each and you should be fine.
