Newbie here, I am setting up TrueNAS for the first time and I have a 4bay drive with 4 identical drives in it and when I try to create a pool it shows this error to start. “Warning: There are 4 USB disks available that have non-unique serial numbers.

I have seen ONE m.2 to sata HBA which may not be terrible & may service your purposes.

Another bizzare and not recommended path forward would be to run a Type 1 Hypervisor such as ESXi or ProxMox and pass the drives through.
