no there's not - currently.

I find them worthwhile to see, as it hints at what the admin or 
scripting is doing, as well as giving hints on when nvme? names may be 
reallocated. I would not remove them for normal storage controllers. 
Perhaps a discovery controller could be filtered out, but I still find 
it useful.
