M1 MacBook Pro "Disk Not Ejected Properly" several times during sleep

Computer: MacBook Pro (13-inch, M1, 2020)

OS: macOS Big Sur 11.0.1

External Hardware involved:

- OWC Mercury Elite Pro Quad RAID 4-Bay (USB 3.1 Gen 2 cable) (4 hard drives, 2 volumes, both mirrored) (RAID is brand new, drives are less than a year old)

- OWC Thunderbolt 3 Dock (brand new)

Problem:

I'm having an issue with hard drives being ejected randomly on my mac. While the computer is unused, I'm assuming during sleeping, my hard drive is being ejected improperly. I get several of the "Disk Not Ejected Properly" notifications whenever I come back to my computer if I leave it overnight. It's happening every 3-4 hours, sometimes more. (See photo of notifications for more info)

I've confirmed that the issue only happens whenever the hard drive is connected to the OWC Thunderbolt 3 Dock. When the drives are connected directly to the computer, it doesn't have the ejection issue at all. I need to use a dock because the computer only has 2 ports and I have several peripherals to connect to the computer.

The OWC dock is brand new and worked fine with the old Macbook Pro. The hard drive enclosure is maybe 2 months old, and the drives should still have plenty of life left. I initialized and verified all of the drives before creating the RAID arrays.

Solutions Tried:

I've tried unchecking the "Put disks to sleep whenever possible" checkbox and that didn't help. My assumption is that it has something to do with Apple's "Power Nap" feature, I heard there were changes with it on the new M1 Macs, but I don't really know. Anyone have any thoughts? I'm really not sure what to try at this point. I have another dock on the way that I'm hoping will fix the issue.
