splunk install app from an insecure URL

Hello, I'm trying to install an app via command line similar to this: splunk install app https://self_signed_cetificate_server.org/splunk-app-for-unix-and-linux_523.tgz -auth admin:StrongPassword Since the server is using https with a self signed certificate the installation fails. Are there any options of the "splunk install app" command that would allow me to use an insecure https server ? Any way of doing this without downloading the file first with a separate tool like curl or wget?
