De Vries crashed during Friday qualifying for last weekend's Azerbaijan Grand Prix and then suffered another incident in the race when he tapped the inside wall at Turn 5, having to retire with a bent front-left toe link.
The 2020/21 Formula E champion is still chasing his maiden points, with fellow rookie Logan Sargeant the only other driver yet to score as 2023's tight midfield battle has opened up opportunities to sneak into the top 10.
Team boss Tost has defended the Dutchman and made comparisons to previous Faenza alumnus Sebastian Vettel, who also had a propensity for damaging his car in his rookie days before establishing himself as a major force.
"There's, as I always say, a learning process and a crash period," Tost said on Saturday in Baku. "Because if the drivers don't crash, they don't know the limit.
"This is a credit you must give them, otherwise it doesn't work.
"And there was no driver not crashing. I remember that Sebastian in the first races came back the first lap most often without the nose. That's part of the game."
