Disable stock parking sensors on Prius 2010

I have a Prius 2010 for which the rear bumper has been totaled. I found a new bumper on-line new for not a lot of money! But it has no holes for the stock parking sensors. I just disconnected those but now the car beeps when I put it in reverse because it does not 'see' the parking sensors. I can hit the 'ignore the parking sensors' switch in the car to have the noise stop, but I'd have to do that any time I start the car.

Is there a way that I can configure the car just to ignore the parking sensors?

 

I'm sorry for posting in the wrong forum!! Thanks for the hint, and indeed I can press that button but the problem is that I need to press it _anytime_ I start the car. I was looking for some thing I could do have the park sensors (preferably just the rear sensors) not work.

Would there be someone that can move this thread to the proper forum? Otherwise I'll open a new thread in the right place.

 

In the mean time, I decided just to drill holes in the bumper in about the right places and replace the sensors. It was a lot less difficult than I was fearing and the result is better. Drilling in the bumper is very easy, and I had the old bumper to test on, to ease my anxiety about how difficult the drilling might be!
