Hello AJ,
I recommend having a read over SSPR:
Enable self-service password reset
Microsoft Entra ID lets you enable SSPR for None, Selected, or All users. This granular ability lets you choose a subset of users to test the SSPR registration process and workflow.
As far as using Graph, I do not believe you can see this information/settings.
If this is helpful please accept as answer or upvote.
