No, that will not work. The Pro Display XDR does not have downstream Thunderbolt ports for connecting devices, it only has a single upstream Thunderbolt port for connecting to a Mac. The 3 downstream ports on it are USB-C only, not Thunderbolt - while the connector is physically the same, you cannot plug a Thunderbolt device like this adapter and/or a Lacie Thunderbolt disk into the ports on the XDR. You can only use USB-C disk drives with the XDR, any Thunderbolt devices must be plugged directly into your Mac.
