HL8548-G at+gpsconf=10,2 not working

Running at+gpsconf=10,2 gives ERROR but 10,0 and 10,1 work.
I checked the available parameters with at+gpsconf=? then it turned out the option 2 is not supported.

+GPSCONF: 10,(0-1)

According to the manual, however, the option 2 is suported in HL8548-G, why is this happening?

revision ID is

It turned out that option 2 is supported from the version, so I need to upgrade the firmware basically.
