Try with --dms-list-stored-images. It will give you a list of the
installed "modem" (firmware) images plus a list of "pri" (carrier
config) images. You can probably switch the module to every "pri"
carrier config, as long as there is a "modem" firmware with the
expected "Build ID".

Here's an old email with some example output:
https://lists.freedesktop.org/archives/libqmi-devel/2017-January/002000.html

P.S.: the flag indicating which "modem" firmware is currently selected
is BROKEN in Sierra modules, so don't rely on the ">>>>>>>>>>
[CURRENT] <<<<<<<<<<" indication of the "modem" list. The "current"
flag in the "pri" list doesn't have problems. I've reported that issue
to Sierra in their forum a couple of times, but they don't seem to
want to fix it... :/ You can also use --dms-swi-get-current-firmware
to get a correct output of what's currently running.
