Re: Dell TB16 Dock Madness
I'm using the Dell WD19 TB with Precision 5540 (basically a rebadged XPS15), and would thoroughly recommend it, works great with Ubuntu.
For updates, I get firmware and BIOS updates for both dock and laptop through fwupdmgr. Have you tried this?
fwupdmgr get-updates && fwupdmgr update
