Selecting cellular vs wifi before app start

Hi forum,
I use this line in COMPONENT_INIT:

le_data_SetTechnologyRank(0, LE_DATA_CELLULAR);

Does anyone know of a system-wide way to accomplish this, such as in a config setting such as in a .sdef or .adef file?

I would like the device to startup as fast as possible, and my concern is that it might be taking time trying to establish wifi when that is not ever available in my case.

It seems like there would be a lot of comm activity before app boot time, and that there is probably a way to establish the technology preference without relying on an app to do it.
Any help would be greatly appreciated.
