I do not recall doing anything to "enable" LibreDrive for the Asus drive
"Enabled" here mostly means that the firmware accepts "vendor commands" that allows MakeMKV to perform volatile "microcode update" on the drive (i.e. "hacking" the firmware
temporarily, more or less) so that it can use a "bypass" to read AACS VID for VUK calculation and disable bus encryption and so on.
All the LibreDrive supporting ("enabled") Pioneer firmware has never been made to reject those "vendor commands". In other words, they are "inheritly Libre". FWIW, that's what "Firmware type: Original (unpatched)" means btw -- "patch" here refers to
"MK-isation" of some of the newer LG firmware.
And as I just mentioned, newer LG ("HL-DT-ST") firmware has been made to reject those "vendor commands" and therefore drive comes with such firmware requires to be flashed with an MK firmware (or older firmware that is "similar" to Pioneer firmware) to be Libre -- NOT necessarily one for the exact same model. (Therefore, in some sense "Enabled" also means "flashed with an MK firmware", hence "Possible, not yet enabled" -- with the "Possible" mainly refers to "Drive platform: MT1959".)
(FWIW, AFAICT the "vendor commands" is still just a standard SCSI command. "Vendor" here really refers to "arguments" that may be blocked. I could be wrong though.)
P.S. Probably we have "met" on an SE site. If that's truly the case, here I am greeting you with my verbiage again
