UPDATE: DID IT! A LONG TIME AGO (AND WASN'T ABLE TO COME BACK TO IMMEDIATELY UPDATE EVERYONE)
For those who are about to ask for the same question on the internet this is the answer.
 
I used hd-idle and it worked perfectly among my drives.
 
follow this guide:
https://www.htpcguides.com/spin-down-and-manage-hard-drive-power-on-raspberry-pi/
 
ymmv depending on the drives you use (if the hard drives can support it)
 
hd-idle perfectly worked on my old western digital and seagate hard drives but not perfectly on my seagate barracuda green hard drives (I think because of power management within the firmware of my hard drive so I had to turn off hd-idle altogether)
 
you can find on the link other alternatives to the one I used in case it didn't work for you
 
thanks for everyone who answered my inquiries!
