Is your feature request related to a problem? Please describe.

No, I haven't seen one.

Describe the solution you'd like

It would be nice if the Diffie-Hellmann encryption would be added to the NPM.
In the terminal it could be done with:
mkdir -p /etc/nginx/dhparams
openssl dhparam -out /etc/nginx/dhparams/dhparams.pem 4096

Describe alternatives you've considered

An alternative way could be to add a description how to add manually without a GUI.

Additional context

It would be nice if there is a slider in a GUI or something like that, so that you could add more security to the communication between server and client.
