Can KVM be used instead? Values in KVM are encrypted, but before they are used they are kept in cache. Are the KVM values stored in cache already encrypted? In this case KVM also cannot be used.

Is this solution safe ? If found in documentation (https://docs.apigee.com/api-platform/cache/manage-caches-environment) that: "Cache is encrypted only in PCI- and HIPAA-enabled organizations"
