How do you use "is defined" in a script? (lemmy.world)

I'm trying to get a script built. I want to check if a variable exist and include it if it does. Just really struggling to figure out the formatting. Something like

script:
  sequence:
    target:
      entity_id: "{{ entity }}"
    {% if variable is defined %}
      data: "{{ variable }}"
    {% endif %}

When I tried playing with omit in the template editor I got an error about omit being undefined so probably not built in. Bummer because that would be a very elegant solution to this. I'm going to put this down for the night and try picking it back up tomorrow. I really appreciate all the suggestions. Hopefully it will lead me to a solution.
