Now, for your specific case, I notice that the toggle takes up a lot of space and seems a bit redundant. So, I think you can use something like this:
<label>Allow Virtual Appointments</label>
<option>Yes, in-person and virtual appointments</option>
<option>Virtual appointments only</option>
<option>No, do not allow virtual appointments</option>
