in /user/plugins/plugin_name/plugin_name.yaml
built_in_css: false

in my case - /user/plugins/login/login.yaml

I hope this helps someone

even better, create a "plugins" folder in the /user/config/
and put your plugin_name.yaml into this folder
then override options
in my case - /user/config/plugins/login.yaml

correct me if I'm wrong

correct user/config/plugins/login.yaml is the correct location.
