hide modify radio button of SdWelcomeMaint

Hi,

I am using Installshield 2015. I have project which is installscript msi. I am using/calling SdWelcomeMaint function which display 3 radio buttons as modify, repair and remove.
My requirement is I want to hide modify button and display only repair and remove radio buttons.

Is this possible? if so, what are the steps to do it?

Thanks.
