Execute some bash script before docker-compose build triggered by command

Question

Is there a way before building of docker containers with docker compose to execute a bash script?

something like

version: "3"
before_script: //execute my local script 
services:
  database: ....

No there is not.

you can make a custom bash build script that executes your local script before starting the containers

why is there no such an option????

Because the docker-compose devs say it will "break compatibility" because, for instance, Windows doesn't have bash by default. github.com/docker/compose/issues/6736

I don't see how the compatibility argument makes sense. Docker compose can use Dockerfiles or inline Dockerfile syntax and those have a SHELL= command. So there is nothing to stop there being a stage that is platform dependent if that particular project is cross platform. It would be more useful to have it than to omit it on made up grounds. e.g. I want to unmount a bind mount during build to prevent files from being copied to the image. The --exclude seems very broken and unreliable.
