Probably either wait for some other provider to build helm charts, roll your own k8s YAML for Redis based on the helm chart and with standard Redis OCI images, or migrate to a different, but compatible service like DragonflyDB if you don’t need modern Redis features (not suggesting Valkey because they are also entrenched in Bitnami and offer it as the official chart source).
