How to work DPD on AD9375 with DPD parameters set by user

I have a question about how to set parameters and work DPD on AD9375 with parameters set .

I confirmed that DPD works on AD9375 with DPD default parameters.

but there is still room for improvement in terms of Adjacent Channel Leakage Radio (ACLR).

So, I tried to change DPD default parameters to custom DPD paramerters by using API function (MYKONOS_configDpd()) and evaluated ACLR. Conseqently, ACLR was unchaned, compared to ACLR with default DPD parameters. 

I'd like to know how to work DPD on AD9375 with custom DPD parameters.
