When trying to Configure NB-IoT Features , to disable SMS service

IoT Modules LPWA Module
1

the execution of AT command was successful but in Attach request , add_update_type we are getting add_update_type = 1 (0x1) (SMS only). AT Command used is AT command used : AT+QCFG=“nccconf”,40

From the AT command manuals we can see that
Hexadecimal value. If any bit is set to 1, it means the corresponding feature is enabled, otherwise it means disabled. The specific meanings are as follows:
Bit 0 Enable or disable the use of EMM_CP_CIOT
Bit 1 Enable or disable the use of EMM_UP_CIOT
Bit 2 Enable or disable the use of EMM_S1_U
Bit 3 Enable or disable the use of EMM_ER_WITHOUT_PDN
Bit 4 Enable or disable the use of EMM_HC_CP_CIOT
Bit 5 Enable or disable the use of EMM_SMS_ONLY
Bit 6 Enable or disable the use of EMM_PNB_CP_CIOT
Bit 7 Enable or disable the use of EMM_PNB_UP_CIOT
Bit 8 Enable or disable the use of EMM_EPCO_CIOT
Can we disable SMS feature support using AT command ? , if yes wat is the procedure/AT command to change that ?
From the QXDM output we can see that , add_update_type = 1 (0x1) (SMS only) is always set as 1 .
