google storage - signed urls with uniform bucket level access

[codergolem]

Is it possible to create a signed url when the bucket has uniform bucket level access but not a publicRead policy? The documentation says that when using uniform bucket level access the setting GS_QUERYSTRING_AUTH should be set to false, causing that all urls will be generated non signed, but this assumes that the objects are public so they can be shared that way.
But in my particular case I have uniform bucket level access and the objects are private, but I still want to share some of them via signed urls, is this somehow possible?
Looking at this code I infer is not, but maybe there is a way.

It is possible, and you can set GS_QUERYSTRING_AUTH to True with uniform bucket level access without publicRead.
