Despite protests from both sides, the match is expected to move on in Madrid with the victor representing South America in the World Cup Championship.
The game was set to be played next weekend in the Spanish capital with the tie level at 2-2 following the first leg of the final at Boca's La Bombonera.
Fans shattered windows of the bus with projectiles and pepper spray was sacked by police, leaving several Boca players needing to be taken to hospital with injuries. It will also make the match less competitive.More news: Kareem Hunt will be interviewed on Sunday morning
River, who were fined $400,000 and ordered to play two CONMEBOL-organised games behind closed doors due to the bus incident, insist the actions of those who threw missiles at the vehicle "are in no way the responsibility of the club" as security forces should have been better prepared in the area.
Infantino then told AFP the Madrid game would be "a festival of South-American football".
From next season onwards, the final will be played in a single match at a neutral venue - a decision which CONMEBOL had already taken before last month's trouble.
In a sign that despite River and Boca's protests the game will go ahead, several Argentine journalists have posted on Twitter details of where the two teams will train in Madrid next week in the run up to the contentious fixture.
"I'm sad, CONMEBOL had the most hard job".
