I would say there is nothing Aryan or Dravidian about snakes.
We also know that snake worship was a feature of the scythians.
"Snake as a symbol, is represented in almost all mythologies, and is associated with land fertility, female energy, water, rain, on the one hand, and the hearth, fire (especially heavenly fire), and the male fertilizing beginning on the other.
Living in our steppes Scythians worshiped snakes, believing in their descent from the supreme god Papaya “snake-legged” goddess Api. This “women-snake” is the mother of the Scythians the founder of the Scythian tribes is often depicted on billboards, quivers and armors of warlike nomads. The Slavs associated snakes with Perun. Snakes had a few values and purposes (as characters). Images of snakes – small snakes decorated ancient vessels with water. Snakes of Perun suites symbolize divine clouds, lightened, powerful outburst of the disaster. These snakes are hydra-headed. You cut one head and the other will grow and throw fire (lightning). Firedrake is the son of the sky mountains (clouds). These snakes kidnapped beauties (the moon, stars, and even the sun). Snakes can quickly turn into a boy or girl. This is due to the rejuvenation of nature after the rain after each winter. Snakes are guardians of untold treasures and medicinal herbs living and dead water. Hence the snake-doctors and symbols of healing are taken from this." https://skifska-etnika.com/brand/en/...cient-scythia/
The Deo of Nysa (wherever that may be - Anatolia, Crete, or Bactria, Oeso?) followers, we know from stories told that they were a snake cult.
Alexander's mother:
"all the women of these parts were addicted to the Orphic rites and the orgies of Dionysus from very ancient times (being called Klodones and Mimallones)1 and imitated in many p229 ways the practices of the Edonian women and the Thracian women about Mount Haemus, 8 from whom, as it would seem, the word "threskeuein"2 came to be applied to the celebration of extravagant and superstitious ceremonies. 9 Now Olympias, who affected these divine possessions more zealously than other women, and carried out these divine inspirations in wilder fashion, used to provide the revelling companies with great tame serpents, which would often lift their heads from out the ivy and the mystic winnowing-baskets,3 or coil themselves about the wands and garlands of the women, thus terrifying the men."

Some have even noticed that the Malta folk on the Baikal had snake motifs - very suprising that far north in the LGM.
"On one side of the plate we can see three snakes. The snake is rare in northern hemisphere Paleolithic art, presumably because the cold conditions precluded a wide distribution of snakes. In addition, it can be seen that the snakes have very broad heads, as though they belong to the Cobra group - yet Cobras are now known only in southern asian localities." https://www.donsmaps.com/malta.html
