In the CSM.ini file of the mod you have these options:
[BlackFlag]
HideJumpStartFlag =
HideCutTrackFlag =
DisableSlowDownJumpStart=
DisableSlowDownCutTrack =
EnableDriveThrough =
DisableBlinking =
ForceRetire =
So probabely if you set 1 or 0 you can adjust them, not sure but thats the only thing i found in a CSM mod to adjust black flag, hope it helps andré !
