How to request a temporary On-Premises trial license key for a CDP Private Cloud PoC?

"Hi Community, our team is planning to evaluate CDP Private Cloud Base for our internal big data modernization project. We want to set up a small 3-node cluster for a Proof of Concept (PoC) on our local infrastructure. Since the repository is now password-protected, how can we officially request a temporary trial license key and repository credentials to test the installation with Cloudera Manager? Any guidance would be highly appreciated."
