I can’t see where MT Pro is introducing any traffic.
I do know that Korg has their own drivers and maybe that is what is happening. Maybe try the generic driver. Check this post.
Also, I believe the drivers for nanoKONTROL Studio introduce bluetooth so maybe it has something to do with that. Again, I would see no reason that MT Pro would introduce activity.
