A draw in Wednesday's game at the Maracana Stadium would be enough to clinch first place and avoid a probable meeting with Argentina in the last 16.
But France full-back Mathieu Debuchy says his team-mates will aim to finish with a flourish to maintain momentum.
"We need to avoid taking our foot off the gas even if there is not a huge amount at stake," Debuchy said.
"We want to win this match and maintain our positive dynamic in order to prepare well for what is to come,” he added.
France's huge goal difference of plus six also means they could even lose to Ecuador and still win the group.
Switzerland, level with Ecuador on three points but trailing on goal difference, would then need to win big against Honduras to have any chance of advancing.
France's comfortable position means Deschamps can shrug off the loss of suspended midfielder Yohan Cabaye with Lille's Rio Mavuba set to come in.
Deschamps can also contemplate replacing centre-back Mamadou Sakho - who came off against the Swiss with a thigh problem - with Laurent Koscielny.
Eliaquim Mangala is also on standby as Raphael Varane has been laid low by a stomach bug.
With Ecuador favouring a direct approach, Wednesday's game could well be a high-scoring encounter.
Wingers Antonio Valencia and Jefferson Montero will provide the ammunition for Felipe Caicedo and the in-form Enner Valencia, who has three goals so far.
Reinaldo Rueda's Ecuador only need to match the Swiss result in the other game to reach the last 16 for the first time since Germany in 2006.
Should Honduras win and Ecuador lose, the calculators would need to come out to work out who joins France in the last 16.
