Yes!! The Dell WD19 was notorious for that. My wife’s company used those - we couldn’t leave her WFH dock connected to our home network because of the wild broadcast storms causing our core switch to stop processing frames from her home office desktop switch. My org used HP Dock G5 units which behaved much better (besides the occasional firmware update killing video output until a power cycle, and inconsistent MAC address pass through between hardware revisions).
