Default [Q] Any way to change subscription mode from NV to RUIM

We want to use Nexus 5 or other carriers CDMA network, e.g. China Telecom, but according recent information recent, seems Nexus 5 used NV subscription mode, that means get ESN code from NV, this is method used by Sprint.
Is there any possibility to switch the subscription method to RUIM mode to get ESN or pESN code from RUIM?
I suspect this is the key to enable it on other carriers network besides change MEID or IMEI directly in NV ROM.
Does it work to add codes below in build.prop?
ril.subscription.types = RUIM
Look for your kindly help.
Thanks in advance.
