ACC prevents overtaking

Hello forum, at my 2016 León FR it happens again and again to me that the ACC prevents me from overtaking a truck. This starts from about 120, 130 KM/h. As soon as the truck enters the detection area of the ACC, it starts panicking to brake. A little later the ACC notices that the reaction came far too early, because the distance is still quite large, and stops braking. Only: then the momentum is gone, and I can no longer thread myself into traffic on the left lane. A uf the empty Spanish motorways the traffic is so thin that you can often drive out in advance, but in Germany and France the traffic is simply too tight for it. Is there a way to prevent the panic brake without constantly shutting down the ACC?
