I have no idea whether the drive does support it or not.

Anyway: no, the world ain't as easy as you think it were. :)
Supporting features is not as simple as adding a #define to a header
file.  The actual work is hidden inside a driver, the #define is only
the interface definition of the driver to the outside world.

The st(4) driver in FreeBSD-current does support the MTRETEN command,
and of course, mt(1) has been updated to include it.
