CSFB method PSHO or Redirection

Hi Dear Friends.
Please, in Ericsson LTE what parameter change CSFB method, between PSHO or Redirection?

I know for redirection is feature CS Fallback to GERAN and UTRAN, and for PSHO is feature PSHO-Based CS Fallback to UTRAN.

But when I have two features actived, how I can choose only one?

I can tell you for Huawei (I have been experimenting on this recently).
