On the initialize form rule, you have several ways to achieve that:

Either use the transfer data action and set the radio button list control with the smartbox box entry ID which matches the No value

OR

Execute a smartobject method (load or list) and on the 'Output Mappings' tab set the value for radio button list control.

Thanks for the response.

I am not sure about the ID(No/yes) of the radio button list.

The radiobutton list values are in datatype Boolean(lookup).

When you populate a radio button list based on a smartobject, you have to select the Value/ID field on the data source configuration window. If you select the Boolean field as the Value then you can use a transfer data action and set the control with False, like the image below shows.
