Hi @muralipraveenr1
I do not think this is possible.
You can blacklist some commands (like: ln, dd, openssl, curl, wget, python, python3, perl, ruby, sh, bash, dash, zsh, base64, nlserver, node, phantomjs, java, awk, nc, telnet, ssh, scp, ftp) in exec part in serverConf.xml
You may try with execCommand(systemCommand, false) which should disable output.
If not, you may consider using Bash script inside JS to avoid this command.
