I have a neat HPE microserver Gen10 plus running FreeBSD 13.0. Super nice experience for a small home NAS.
An "issue" I noticed is that my four main storage disks (ZFS raidz-2) are spinning down and back up quite a lot. I know that I was thinking about disk spin down when I was initially setting up the system but according to my memory I never committed to that - but that is unlikely false.
I'd like to figure out how to disable the disk spin down.
So far I have checked the BIOS/UEFI options and I couldn't find any related option(s). Therefore, I assume that this is a FreeBSD setting.
Could somebody shed some light on how to properly figure out whether spin down is enabled and how to disable it? I seem to find "controversial" information on this topic.
I assume that I want to look at

camcontrol idle

and camcontrol epc
