Scan specific network types in SC20

I need to configure the type of network (LTE, GSM, WCDMA, …) and the band (B1, B3, B5, …) to which the SC20 module can connect.
I found that the bands for different types of networks can be configured using the AT command “AT+QCFG=“band”” and SC20 supports it.
But the command “AT+QCFG=“nwscanmode”” with which you can configure the type of network it does not support.

Sending AT+QCFG=? I get this response:
+QCFG: “hotswap”,(0,1)
+QCFG: “simInsertLevel”,(0,1)
+QCFG: “pppDownConfig”,(0,1),(0-600)
+QCFG: “band”,(0-200),(0-7FFFFFFFFFFFFFFF),(0-7FFFFFFFFFFFFFFF),(0,1)
+QCFG: “simconfig”,(0,1)
+QCFG: “reset”
+QCFG: “dbgctl”,(0,1)
+QCFG: “IMEIlock”,(0,1),<“key word”>
+QCFG: “DumpEnable”,(0,1)

Could you send me “AT Commands Manual” for SC20 or at least suggest how to configure the type of network to which the module can connect (LTE, GSM, WCDMA, …)?

sorry, we don;t have AT commands to configure the type of network.
But i think you can try to write a Android service to do this work. you can refer to the Settings application

I also need to block band 40 on this device, if anyone can help, please explain to me how this is done
