How can I disable or hide a radio button within a TRadioGroup?
I do not see a way to do that. 

I have a radio button that I need to disable for now, but I will need
it later and I do not wish to delete it from the TRadioGroup.

Found one way:
  rgBaseConfigs.Controls[3].Visible := False;

Or:
  rgBaseConfigs.Controls[3].Enabled := False;

Another way: respond to a click on that button with an error message
and reset the active button to another button.

Yet another way: accept the action, but do not bother to respond.
