code: public ExpiryPolicyBuilder<K, V> create(Duration create) {
      Objects.requireNonNull(create, "Create duration cannot be null");
      if (create.isNegative()) {
        throw new IllegalArgumentException("Create duration must be positive");
      }
      return create((a, b) -> create);
    }

  Note: Calling this method on a builder with an existing TTL since creation will override the previous value or function.
  
  @param create TTL since creation
  @return a new builder with the TTL since creation
