Disable single radio button in a radio button group

Is it possible to disable a single radio button in a radio group? Something like:
$w(“#radiobuttongroup1”).disable[2] or $w(“#radiobuttongroup1”)[2].disable()
I know neither of the above work, so how would I disable the third button?

You can’t disable one button from a radio button group, it will be all or none.

You can try other options though like setting the options in code and having no label on one button so users would hopefully associate it as not usable, or you simply add a new label like not needed.

Thanks. I think I will switch to checkboxes.
