VolumeSnapshot Support for Storage Class provisioner

Hi,
Is there a way to know that whether the PVC has the volume snapshot ability. meaning, how to check the storage class used by the PVC supports VolumeSnapshot capability?
I am aware that the provisioner of storage class determines whether VolumeSnapshot is supported or not for that Storage Class.

I believe there no property in manifest which tells that provisioner supports volume snapshot?

is the documentation of provisioner is the only way to know?
