Braking assist

[Riley1131]

Can anyone tell me if this can be disabled and if so how to do it on a 2021 t680 with cummins. I was coming down i65 Friday running 75 mph with nothing around approaching a under pass and this thing stabbed the brakes so hard then immediately released them but I nearly lost it. I was grossing 79k with a load of steel on the back. It stabbed so hard I got out and made sure it didn't tear anything up in the brakes. Thank God it wasn't raining.
