FYI, I installed the drive into my trusty old 
Sonnet Echo 15+ Thunderbolt 2 dock connected to a Mac Pro 6,1 (running Monterey 12.7.6) and flashed from there. Some slight modifications were performed to properly fit the drive into this enclosure since the BU40N is considerably slimmer than the previous existing drive (HL-DT-ST CT30F). Basically, just some 3M double-sided tape and rubber spacer rings were required to ensure the drive is balanced, as only one screw mount point aligned from the original included cage.
