No. SCIM (System for Cross-domain Identity Management) provisioning is not currently supported.
You can’t configure user accesses and permissions directly from your identity provider.
If you'd like to provision a new Dashboard user with access to one or more of your applications, you can invite collaborators to the Team for an application via the Team area of the Dashboard and configure their permissions.
If they don't already have an Algolia account, doing this will create a new account for them. Once they log in via SSO, they will be able to access the application(s) that you invited them to.
