Liverpool midfielder Jones and Newcastle United full-back Livramento have both been part of the senior squad before without being used.
England confirmed the news on Wednesday and added Harry Kane is continuing his individualised programme, while Jack Grealish sat out of training with a knock.
Morgan Gibbs-White, Ezri Konsa and Kobbie Mainoo have each pulled out of the squad since it was announced after sustaining injuries over the weekend.
The Three Lions host Greece at Wembley on Thursday and then travel to Helsinki to face Finland three days later, with both fixtures coming in Group B2.
Jones is well known to interim England head coach Lee Carsley, with only two players having been used more under him for the Under-21s in the Three Lions squad for this week's fixtures.
The 23-year-old played 14 times at that level for England under Carsley, level with Anthony Gordon and behind Noni Madueke (19) and Angel Gomes (16).
He was included as part of Gareth Southgate's provisional 33-man squad for Euro 2024, a year on from scoring the winner in the Euro Under-21 Championship final, but did not make the final cut.
Livramento, meanwhile, was part of the squad for last month's victories over Republic of Ireland and Finland but did not receive his maiden cap.
The former Chelsea player has featured nine times for Newcastle this season and has helped his club side to three clean sheets, most recently in last weekend's 0-0 draw at Everton.
