Huawei ME936 not recognizing AT^SYSCFGEX command

I'm trying to force this modem to use exclusively lte network. I delved into modem's user manual, and found the setting. However, the modem is not complying.
I wonder if this is due to ModemManager, or the modem itself? The modem responds to all other AT commands without problems.

systemctl stop ModemManager NetworkManager
systemctl start NetworkManager
ModemManager --debug

mmcli -m 0 --command=AT^SYSCFGEX?
response: '^SYSCFGEX: "00",3fffffff,1,2,7fffffffffffffff'

mmcli -m 0 --command=AT^SYSCFGEX="03",3FFFFFFF,1,2,7FFFFFFFFFFFFFFF,,
error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Message.NotSupported: Operation not supported'

Debug output:

ModemManager[8544]: <debug> [1528932398.434074] (ttyUSB0) device open count is 3 (open)
