Doubs about the compatibility of the QNAVIGATOR with BG770A-GL TE-A

Hi All,
I’m able to comunicate with the EVB through the QNAVIGATOR (v1.69) but fails the check of the registration status because the command AT+CGREG is not supported by the BG77.
Is it possible to replace the command AT+CGREG with AT+CEREG? Does it exist some file configuration in order to define the commands?
