I am a native Sinhalese, and I can speak Indonesian (Bahasa Indonesia) and Tamil. No, we cannot use native languages for CS. For Sinhalese, there is an on-going attempt to invent words or rather put words together to translate a technical term to Sinhalese, but nobody can figure it out. "Download", for example, is literally translated to a word that doubles as taking something down via a crane, and it has become a sort of a joke that the linguistics even attempted to translate. However, in Sri Lanka, English is one of the official languages and university courses are in English, even the non-CS majors. Professionally, pretty much every company is using English for both team and client communication. Other than a few starter YouTubers, I have yet to see anyone meaningfully using Sinhalese in CS. It is a similar situation in Indonesia too, although more Indonesian words are used. Indonesian itself is rather limited due to its limited nature, and borrows many of the words from English and Dutch. The former languages in the archipelago such as Javanese and Sundanese tend to be quite limited for technical literature, but rich with grammar and meaning.
