I'm Debian maintainer for xarray.

https://tracker.debian.org/pkg/python-xarray

Debian/Ubuntu builds packages offline, from a frozen tarball (or possibly a small <5 number tarballs).
xarray requires external objects for both building documentation and testing (we can do testing on our own CI/CD pipelines).
Recent releases use pooch to download/cache test objects. We need a method of stating where the cache is (/home not an option -- that is directed to /non-existant on our build systems).

Can this be implemented, or how do you suggest we proceed?

Best regards
Alastair McKinstry

### What did you expect to happen?

_No response_

### Minimal Complete Verifiable Example

_No response_

### MVCE confirmation

- [ ] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
- [ ] Complete example — the example is self-contained, including all data and the text of any traceback.
- [ ] Verifiable example — the example copy & pastes into an IPython prompt or [Binder notebook](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result.
- [ ] New issue — a search of GitHub Issues suggests this is not a duplicate.
