```python
xr.set_options(diverging_cmap='RdYlBl', nondiverging_cmap='magma')
```
So I think this would work for your use case of updating defaults for all plots in a notebook.

Take a look at https://github.com/pydata/xarray/blob/master/xarray/core/options.py for where we implement options. You would need to then use them in xarray.plot.utils:
