Depends, kernel bypass isn't just about avoiding the kernel, a lot of the cards used are specifically desinged for this and come with much lower latency (as low as 1us to write a packet). Eliminating a kernel copy of the buffer being made will improve the performance significantly, but probably won't get you the same performance as a specialised card which would be what you'd usually go for if it's that important.
