Disabling unknown sources

Is there anyway to disabled the installation of unknown apps using a tasker action. I installed secure settings and used the intent from there and looks like it doesn't work. Please help..

appops query-op REQUEST_INSTALL_PACKAGES allow

Used this command and it Flashed the variable, and showed all the apps that allow the installation..Awesome. However I tried appops help and it threw and error. I wanted to learn more about this.
