DuckDB natively supports multiple S3 compatible object storage providers, like Cloudflare, Google storage and so on. It's documented here:

You can also already use the SET syntax inside Motherduck to query these non AWS providers, but this doesn't persist between sessions, and seems designed specifically to store this kind of information securely and durably.

Can we have support for this in MotherDuck by setting a SECRET for the endpoint too?

Adding this to would likely involve adding one more parameter to the motherduck function , and would be SO helpful for querying data in existing S3 compatible buckets that are not on AWS.
