It was more than annoying on my system - acknowledge the alarm and you shut it up only for the interval between signal updates - it made passage planning in a commercial harbour impossible until I finally got off my butt and fitted a separate switch to the AIS power feed.
Probably it depends on the plotter, but my Raymarine can be configured no to send AIS alarms. I normally do this in busy areas where I can rely upon my sight, and turn the alarm mode on when cruising in open waters, however I leave the transponder ALWAYS on when sailing (not when berthed), otherwise it would be useless.
