He was nominated for the Virgin TV British Academy Television Awards in 2018 for his work in the adaptation of Sathnam Sanghera's memoir "The Boy with the Topknot", a TV movie.
The award went to O'Byrne for "Little Boy Blue" at the ceremony here on Sunday.
"Thank you Bafta for the Best Supporting Actor nomination for 'The Boy With The Topknot'. It's a great honour for me, for a Hindi medium educated boy from a small town in India whose father was a clerk in the forest department.
"Thank you to the Indian film industry for giving me wonderful opportunities... I was not announced the winner among the four nominees this evening, but nevertheless, I feel humbled and honoured. There is always a next time," he added.
Hosted by Sue Perkins, it was a night of shocks for many as "Love Island" scooped the prize for Best Reality and Constructed Factual, beating out rivals such as "The Real Full Monty" and "Celebrity Hunted", reports dailymail.co.uk.
