Disable logs in MultiLoad and FastExport - Teradata

Question

I'm working with a script in python that will first create mload or fastexport files depending on parameters and then within the script I start those files to insert/export data.

    result = subprocess.run(["{0} < {1}".format(file_type, file_path)], 
                                stdout=subprocess.PIPE,
                                stderr=subprocess.PIPE,
                                shell=True)

example: fexp < .../conf.fx

This however creates logs in /logs folder depending on the application: either MloadUpload.log or FExpDownload.log Is there a parameter with which I could disable creation of log files by multiload and fastexport?
Can I do it from command line or within the config file?
I can't find an option for this anywhere :/
