I do not have this option on my NVR5216. I only have Version, Disk and BPS. I was on V4.001.0000003.2, Build Date: 2020-10-10 . I have updated to V4.001.0000006.1, Build Date: 2021-07-09, but still not have the option.
I remember when I first powered the device on, it was loud as hell, but it settled down during first configuration options and was really silent.
