Hasenhuttl, who faced similar problems at former club RB Leipzig, compared it to alcohol and drug addiction.
"It's something you get addicted to and that means we have to protect the players," the 51-year-old said.
On Thursday, an anonymous English footballer admitted lengthy gaming sessions threatened to ruin his career.
The Sun revealed the unknown EFL player would play popular video game Fortnite for up to 13 hours a day.
"It's something you have to force actively against and I will do this," said Hasenhuttl, whose side travel to Brighton in the Premier League on Saturday.
"I did it in my last club. We had also problems with players - they were playing until three o'clock in the morning before a game.
"You have to help protect them because it's not a small problem. If you are honest it's the same as alcoholism or getting addicted to drugs.
"To protect them means helping them not to spend so much time there. We block the wi-fi in the hotel, for example, in the evening so they can't play any more."
