Toney was this month charged by the FA with 30 more breaches of betting rules after being charged with misconduct in November for allegedly breaching the rules 232 times between 2017 and 2021.
“I can only praise him for his mentality and his character. He is in many ways unique there,” Frank told a news conference ahead of Friday's Premier League match at West Ham United.
“His ability to have that laser focus and go into the game focused on the next action, the next moment and fulfilling his role in the team and pushing the team and helping the team is remarkable."
Toney scored in the 2-2 home draw with Tottenham Hotspur on Monday that left Brentford 10th with 20 points from 16 games.
“For any player, it’s about finding that consistency, no matter what is hitting you. From where you find your extra inspiration, motivation, or whatever it is, it’s different from player to player," Frank added.
“But I don’t see a more determined player, I just see the same Ivan who wants to progress and be better every day.”
