Yes, see https://winscp.net/eng/docs/scripting#configuration

This cannot be set on command-line. You have to configure it in the GUI.

how can I overwrite the log file using command

winscp.exe TESTUSER /console /script="C:\docs\bat\winscp.txt" /log="c:\docs\bat\winscp.log"

I see int he windows gui on the logging tab (window) I can set the overwrite option how can I do this using the scripting or commands?
