How to Disable the use of TLSv1.0 protocol in a Meteor Application

I want to secure my Meteor Application and want to disable the use of TLSv1.0 protocol.
I know this can be achieved by having a nginx layer in front of the meteor application. But I’ld like to know if something can be achieved directly on the Meteor application. Either by setting on the WebApp configuration or other ways.

What makes you think Meteor is responsible for SSL / TLS? Normally it’s the web server’s job to build a secure connection. Meteor sends its data in clear non-encrypted and you proxy it to your client via nginx / apache with an SSL certificate. Specify which secure protocols you want to use in your web server config.
