You can achieve this via default column validation rather than nintex validation by doing the following :

  • Go to list settings > Validation settings

  • Add this formula


  • Try to test now , It should be working properly

For nintex at condition section at this

choicefield  == "" || choicefield  == "No"

If not working Try adding two rule , one for No value and for epmty,
