Urgent - Please help - Keyboard-interactive authentication via Arguments in SSIS

While using sftp from SSIS I'm having terrible issue with password authentication. I'm executing it from my laptop and also WINCSP is on same laptop. I had been to the winscp application and changed the settings of the sftp site by unchecking "By pass SSH-Authentication entirely" and could connect via winscp session. But when executed via ssis I get below issue

here is my connection to sftp

/console /command "option batch abort" "open sftp://welcome:6s1+J<@ftp.XXX.XXX.com:22/" "get /foldername/*.csv c:\sFTPFILES\" "-log=C:\sFTPLOG\log.txt" "exit"

Is there a way to supply not to take keyboard authentication in above code?

I even tried embedding -rawsettings AuthKI=0 in the code but same issue

Use -rawsettings SshNoUserAuth=1
