Is a cold storage style zfs pool possible on my main desktop?

I have a main desktop I use for gaming, development, video editing etc. I just put 4 drives into it and setup a zfs pool to store large video files that will not get accessed often. I setup hd-idle to have the drives power down after 10 minutes which works pretty well. The drives power back on when the mount point is accessed which is perfect, but I'd like for them to stay powered down until the next time I try to access the mount point. They currently power back on when the computer wakes from suspend.

Is it possible to set it up such that the drives only power on maybe on first boot, power down after 10 minutes of idle, and then after that only power on when accessed from the mounted file system? And stay powered down through suspend cycles?

I've seen some solutions/discussions online but they all seem to come to the conclusion that the drive needs to be powered on when waking from suspend and then shut down after a timeout which isn't super helpful.

I have 2x IronWolf ST10000NM0086 and 2x HGST HUH721212AL4200 installed.
