Providing additional arguments to the launch script

[ssj2oshi]

How would i go about adding arguments to the docker start command for this image?
Such as --xformers or --medvram? my first impression is that i would need to commit my own image and 'docker run' it with a new entry point?
Also, has anyone had much luck with xformers & medvram options with Rocm? I'm on an 6700xt with 12gb but i'm crashing with anything larger than 600x600~ish
