is there an equivalent for show-default in az ml cli v2?

**Related command**
```az ml datastore show-default -w workspace-name -g rg-name --query name -o tsv```

**Describe the solution you'd like**
trying to build azure ml pipeline with Github actions, and for using some of the commands I need to use azure ml v2
is there an equivalent for `show-default` command in v2?

**Describe alternatives you've considered**
I tried looking for the `isDefault` key using the v2 command:
```az ml datastore list```
but no `isDefault` key was found on the dictionary
this was the result
```
