GNSS AT commands error with the EC20 mini PCIe

Hello,

I bought an EC20 mini PCIe modue and have run the LTE function on it and its working fine.
But when I started to run the GNSS related AT commands, I just got the return value “ERROR” ( “AT+QGPSCFG?”, “AT+QGPS=?”, “AT+QGPS=1”,…)
Does it mean this module version does not support the GNSS function at all or changing the firmware will fix it?

ATI command returns:
Quectel
EC20F
Revision: EC20CEHCR06A06M1G

OK

Best regards
