There is compressionless cable housing for brakes, but it specifically is labeled for brakes.
When I built up a bike with a TRP Spyre rear brake, the instructions for the brake specifically recommended compressionless brake housing. I used some that was Aztek brand. Jagwire and a few other companies make it too. It was stiffer housing than other brake cable housing. I used it for all but the short length of regular housing which I used under the bar tape between my brake levers and interrupter brake levers.
My road bike came with much stiffer brake housing, I assume it is also compressionless.
