AAV, vent question

Remodeled cabin (not like D. Boone lived in) yesterday, vaulted ceilings, new metal roof, and no thru roof plumbing vent to daylight anywhere, or thru gable ends as we see that occasionally so they don't shear off under snow and ice.

Anyway I think they whacked it off so as not to put a hole in their new roof.

Question: is there any circumstance where vent stack NOT to exterior air is allowed, including AAV ( Studor type / air admittance valve) as my understanding is they too have to be accessible, above insulation, and they still need to have at least one outside vent stack?

thanks

My understanding is the same as your understanding.
