that is why they sell the AAvs
if you run 2 inch all the way up under the sink
and then install the AAv inside the cabinet as high as
possible, above the drain, it will work fine
for probably 40 years..
they are literally used about everywhere you cant
chop the living hell out of the home...
you need to make the aavs accssable under the sink for
long down the road .....
their are some regions and plumbers that frown on useing
them but they are still sold in jsut about every hardware store
in the USA....
