SWAG: set key type for generated certificate

Is there any way to set the key type used for generating the SSL certificate?

Traefik has a keytype option (Traefik Let's Encrypt Documentation - Traefik) and I was wondering if there is a way to set that for SWAG other than meddling with the internal config files and whatnot.

I’d like to generate one with an ecliptic curve of 384-bits.

I checked the docs but couldn’t find much.
