If I understand your requirement correctly, you want to disable one of the options of radio button or dropdown based on the date selcetion. Is that correct?
Unfortunately it is not possible to achieve this. Please note that you can disable entire radio button question but it is not possible to disable one of the radio button option.
One possible workaround it add conditions to check the selection of date as well as the option of radio button / dropdown selection and then show an error message. It is also possible to hide submit button.
