Just deployed Dgraph Scaleway Dev-S instance and have a few questions about it

You can’t disable it. But you can change its offset use --port_offset 2 Get started with Dgraph - all ports will increase by 2. eg: 7082, 5082 and so on.

You can use ACL (Enterprise) or just isolate Dgraph behind and API.

You can use Get started with Dgraph it is similar.

which commands?

Just run it, create an API and done.

Cheers.
