Can we allow public access to the learning module in Oracle Talent SaaS and keep IP filtering on HCM

Summary:

We are implementing Oracle Recruiting Cloud and Oracle Learning Management in addition to our existing HCM fusion application. We currently have IP filtering to allow only internal access. I know we can keep IP filtering on WAF for SaaS and allow a public IP bypass for the Recruiting careers sites, but is there a way we can do it for Oracle Learning, to allow access to learning content? If not directly through a exception on the WAF, can we use an R-Proxy or something similar to allow only access to learning through that
