Support for installing portworx on smaller clouds

Hi all
We are looking into using Portworx but we don’t use the big cloud providers. Instead we use some of the smaller clouds like Digital Ocean and Civo. Since the documentation for them are not provided, I was wondering what kind of support Portworx provides when running managed k8s on such clouds. And if Portworx supports them, how do I install Portworx in those clouds. Note that we are still planning to use storage present in a bigger cloud like S3 or Azure Blob Storage.
