No, there in GAMMA the sequence processing a bit different to what we use in SNAP, That is why I don’t see any necessity of applying ML in InSAR Processing’s sequence using SNAP.

Take a look at this please

Multilooking reduces both the resolution and pixel-size. Do terrain correction to the map projection of your liking and select a pixel-spacing of 10m (for example) and see if that works for you.
