Belfast fighter Agyarko, 28, has won all 16 of his fights, most recently beating Harley Collison in York Hall on 30 March.
Before that, Agyarko beat Troy Williamson and Bahadur Karami in Belfast bouts in December 2023 and August 2024.
Englishman Kelly is coming off a split-decision loss to Kieron Conway in November.
The 31-year-old has 25 professional fights under his belt, with 19 wins, five defeats and a draw.
The fight will take place at Canon Medical Arena on the undercard of unbeaten Dalton Smith’s super-lightweight bout against Canada’s Mathieu Germain.
