The MacRory and MacLarnon Cup finals will be played some time in October.
St Colman's, Newry and St Patrick's, Maghera will meet in the MacRory Cup final while the Ulster Schools SF 'B' decider is between St Pius, Magherafelt and Our Lady-St Patrick's College, Knock.
The games had been scheduled to take place as a double-header on St Patrick's Day before the GAA's entire 2020 fixture list was wiped out by the Covid-19 pandemic.
The Ulster Schools' GAA committee remain hopeful about playing the finals together on the same day.
The winners will not progress to the Hogan Cup after a decision was made to cancel all outstanding All-Ireland Schools competitions.
