Contact default field

Hi all good afternoon

in the guide https://wiki.dolibarr.org/index.php/Module_Third_Parties#Create_a_Contact

I don’t find the way to set as a default form the value=“0” to value=“1” (or from Public to Private) the default field status when you create a contact.

Could you tell me what is the workaround to set as a default a contact as a private instead of public?

many thanks to all community
