"dashboard" need enabled in values.yaml?

[sultra]

1.In the values.yaml file of apisix-helm-chart, does the "dashboard" section enable the "APISIX Dashboard" functionality without the need to install the "APISIX Dashboard Helm Chart"? If not, what does it mean?

2. In the values.yaml file of apisix-helm-chart, it mentions "dashboard.config.conf.etcd.username" and states, "Specifies etcd basic auth username if enable etcd auth." However, etcd only has the "etcd.auth.rbac.rootPassword" configuration, which seems to only allow configuring the root password. How can I set the etcd username and password for the dashboard?
