Surprisingly the map and lighting nodes shows that we have ATM in Delhi region which is situated at the northern region.
There was one attempt to install the bitcoin ATM in Bengaluru which is situated to Eastern India region but it was failed attempt and it was seized on the following day of installation.
I also heard about that incident about Karnataka police seizing that bitcoin back in 2018 because it was setup without any permission of the authority and btc is not legal tender in India although there are now tax regulations for investors.But according to this article there are two ATM's around Delhi
India already has two Bitcoin ATMs/tellers in and around Delhi as of now. Prior to this, a Bitcoin ATM was apprehended by the Karnataka police in Bengaluru back in 2018 as it was illegal and set up without any approvals from the authorities concerned.
