Sorry for the late reply. I received a response from support. Albeit, not a particularly helpful one. They pointed me in the direction of the vIDM documentation. In reviewing this information, I found a few general statements that I "can use a third party SAML 2.0 provider." I was hoping for something a little more definitive stating that it is compatible with specific or any SAML 2.0 provider, but haven't found this information to date. I will close this question.
On a side note, we will begin configuring IBM Security Access Manager integration with SNOW and vRA 7.x in late October or early November. If anyone is interested, I can ask our team to provide documentation for the configuration.
