Lowering VRAM usage - --lowvram argument not accepted?

[CB]

Hello, I am running this on a 12GB card with a local LLM, and I noticed when I used --help I got usage information from the stable diffusion webui.
However, I am unable to pass arguments to this module, and --lowvram is of most interest to me.

I ended up changing modules/cmd_args.py to make --lowvram default to enabled, but is there any other way to pass arguments to stable diffusion?
