"Nobody knows how to issue this command or knows if this command works on their drive off the top of their heads."
Sure they do.
You overwrite the drive with a known large file and then check the checksum of it.
It doesn't matter what kind of mumbo-jumbo the SSD is doing - it doesn't have phantom-double-capacity hiding in there ... if the (drive sized file) you wrote checksums out, you're done.
And if you're paranoid, do it a few times with different (drive-sized-files). Quick and easy and faster than googling anything.
