While you can disable all Device Manager notifications for any given computer, you cannot disable notifications for specific devices, no. But you've described a very common situation that at least several other users find themselves in. We definitely want to increase Kabuto's flexibility and control regarding this kind of thing, and we already have plans to do so
In the meantime, I recommend either disabling Device Manager notifications for selected computers, or simply taking the repeated Device Manager notifications from those selected computers with a grain of salt. I'll keep this thread up to date, though!
