Ok after some research I kinda answered my own question
DNM, Enrolado and Convenio are now all DEOX.
RENAPER, RNR and Interpol are still mail (I would guess Interpol will move to DEOX soon too).
Div. Antecedentes is obviously still in person too as one needs to be fingerprinted.
I am still wondering why the judge in question in Juzgado N1 delays the oficios from Interpol and Convenio until after the fingerprints are in...
