In Hyundais this can be disabled by long pressing on the lane keep assist button on the steering wheel. Its the one with a couple of white lines and a steering wheel between them.

You might be able to do similar in the Nissan.

Of course, you have to do this every time you start the car thanks to EU and UK law.

In the Nissan, you can customize all of these things and the car stores your configuration, you just have to press two buttons on the steering wheel every time you start the car to load it. And with those custom config loaded, I find the car really nice to drive. We (I and the family member) have gone through all the safety feature options and made a config which we like. Which mostly means just turning off a bunch of stuff, including the auto-crash and the obnoxious beeping which tells you you're going above (what the car thinks, sometimes incorrectly, is) the speed limit.

Doesn't help when you haven't driven the car in a while so you forget to push those buttons and the car reminds you by automatically turning the wheel towards oncoming traffic :(
