Default [Q] CPU undervolt without root, franco kernel

Hi

Does anyone know if it is possible to set undervolt (and max frequency) with franco kernel and stock rom, without root?

By using init.d or something?

If possible could someone point me in the right direction?

I'm asking because i need to use some apps, that require that the phone is not rooted, and the only thing i use root for is setting CPU undervolt.

Thanks
