is there a way to enable GTAV scripts in FiveM singleplayer by using RequestScript ?

    if (ShutdownAndLoadMostRecentSave()) then
        ShutdownAndLaunchSinglePlayerGame()
        DoScreenFadeIn(100)
    end

i use this code to transition to singleplayer, would like to know if gtav scripts are enabled in fivem.
