Have you considered just turning it off? I would wager you are competent to keep the car in the lane yourself.
On the long drive home from picking up my 2023 Sportage HEV, I was forever being bothered by an audible warning if I got near the center line on the interstate. It was usually a matter of changing lanes on the not crowded interstate without always signaling first.
In any event, my first priority was to get the warning turned off. Somehow I figured how to do that in the menus. I have been driving for more than 60 years and it it comes to the point where I cannot drive the car without assistance, I will give up the keys.
