SAE emergency alert and lumia 640XL

[scandiskwindows9x]

i was wondering if my phone supports the emergency alerts SAE in Chile or at least the american alert system, have not found the setting in my phone and watching this page

https://sysdev.microsoft.com/en-us/Hardware/oem/docs/Customization/Emergency_notifications

looks like my phone is not compatible with any scheme of emergency alert , is any way to get iside the mode developer or even with an file enable it or check if is enabled or hid the menu from user, my phone is imported from Hong Kong and i have no idea if there is an way to enable it.

my phone runs windows 8.1
best regards
Francisco
