Restriction to add some fields in key user adaption in Fiori

Hi Team,

I am checking the key user adaption feature in FLP. I have a smart form with CDS and am able to add the fields, which are declared in the CDS in run time. But i have to restrict some fields from addition using adaption.

Experts please suggest me how to achieve this.
