I believe they discontinued brunch at Narcoossee's early last year or maybe even the year before- well before the park & resort closure. It did look good. If you're looking for a brunch spot we love California Grill - Sunday only, tough reservation to get, & unknown how buffet part will be handled post-COVID. Wine Bar George in Disney Springs has a great brunch on Saturdays and Sundays. I've not been but have heard the Raglan Road brunch is fun too.
