The game is scheduled to begin at 7:30 pm on January 3, at the My Dinh National Stadium in Hanoi.
A win will help Vietnam advance to the semi-final round as winners of Group B and avoid Thailand, which already qualified for the semi-finals, along with Indonesia.
Vietnam lost to rival Thailand in the semi-finals at the AFF Cup in 2021.
Myanmar coach Antoine Hey said although his side has already been eliminated, the team will play their best and strive for a good game against Vietnam.
At the same time, Malaysia will clash with Singapore at Bukit Jalil Stadium in Kuala Lumpur, which is expected to be an exciting match since both have a chance to advance to the next round.
