Having made his United first-team debut against Astana in the Europa League in November 2019, the 20-year-old defender gained further senior experience on loan at Sky Bet League Two side Salford last season.
Bernard made two substitute appearances for United in pre-season friendlies this month and is now set to test himself at Championship level by making a loan switch to promoted Hull.
Another United academy player is also on the move, with Charlie McCann understood to be joining Scottish champions Rangers.
The 19-year-old midfielder is expected to link up with the Ibrox giants' B team in a deal that could reportedly rise to £750,000.
