Is there a noun to describe the status of something being "indoor" or "outdoor"?

I'm not a native English speaker, and I'm searching for a noun (that may not exist?) that would help me describe if something is happening "indoors" or "outdoors".

For example, instead of asking, "Is this activity indoor or outdoor?" I would like to ask, "What is the xxx of this activity?"

Indoorness, outdoorness, etc., don't seem to exist. Does anyone have an idea?

I’m not aware of a noun for this. In practice, I would guess and ask if I’m correct: “Will this dinner be indoors?” Since there are only two options, this works well enough. Words get created to fill a need, and this need isn’t common enough to bother.
