well you have a couple of options and which you chose depends on what you are trying to achieve.
1. if you simply want a hole you can use a curve and project it on to the nurbs surface and then perform trim
2. if you want to combine the parts with a fillet then you'd insert one so that it penetrates the other and perform a fillet operation (note both parts would have to be nurbs surfaces).
