Can anyone tell me how to disable this un needed and irritating notification?

 

Try turning off the LDA and turn off the sway function or reduce the sensitivity or all three. The system has detected you not staying in the middle of your lane frequently. On its max setting it can become annoying.

 

That setting was the very first one I had to find and turn off after buying my car and driving home through the ozarks. I found it to be very annoying.
