Is it possible to hide schema blocks by default?

I would like to have a text block but only show it if the checkbox is checked, is this possible?

{
            "type": "checkbox",
            "id": "corner_image",
            "label": "Corner Image"
          },
          {
            "type": "image_picker",
            "id": "step_corner_image",
            "label": "Step Corner Image"
          },

Try this:

{% if section.settings.corner_image %}
your code
{% endif %}
