Specify Cipher for MQTT

Is there a way to specify the preferred openssl TLS cipher in node-red? For example,

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

Thanks in advance!

The settings are in settings.js and the object is, I think, actually that of the underlying NodeJS TLS settings. So have a look at the NodeJS docs for what you can put in there.
