Using a Raspberry PI to manage USB HDDs as network drives

So i'm looking to use my Raspberry PI 4 to connect one of my WD MyBooks(14T) to use as a backup system.

I looked around, is "Open Media Vault" what i'm looking for?

Currently the WD is connected to the USB port on my Synology desktop nas, but my new Unifi UNAS8 pro doesn't have usb ports. So i'm looking for a solution using what i also have on hand, which is two un used Raspberry PI 4s that used to be hosts for Unifi home networks before being switched out for Dreammachines.
