How to sigint a schedule:run command that is using tty mode to run scheduled commands in background, after it finished?

and #50085 (comment)

if using tty mode true, the stdout from the background commands that are triggered in a shell by the scheduler (proc_open function) is being displayed in stdout.
The schedule:run command finishes before all the scheduled commands finished so I guess that is why it hangs and waits for output from them.

Question is: Is there a way to SIGINT the schedule:run process after all the scheduled commands finished?

I guess it is not recommended if even possible. Found a working alternative via queues. #50085 (comment)

I realised that the scheudle should wait for all the children to finish to catch the logs and if those take 5 minutes, it is not the best scenario.
