The War Elephants head into their return encounter against Malaysia in a good position to make the final after both sides played out a 1-1 draw in last Sunday's first leg at the Bukit Jalil National Stadium.
But while a 0-0 draw would be enough to send them through on the away goals rule, Schafer insists his side will not be going for the victory in front of their own fans at the Suphachalasai Stadium.
"Tomorrow [Thursday] we will go for a win," he said at Wednesday's pre-match press conference.
"We can't hope for the score to remain at 0-0 for 90 minutes. It is too risky."
Schafer will have to watch the game from the stands after he was sent off on Sunday for dissent, an incident he describes as a misunderstanding as he claimed he was directing his anger at his players.
Nonetheless, the German does not believe his players will miss his presence by the touchline.
"The referee made a mistake but everyone make mistakes," Schafer added. "I was talking to my players and he thought I was talking to him.
"The team doesn't need me on the bench. They know what needs to be done but if in any case they need me around, then it will be a problem for us."
The ex-Cameroon boss did however concede Thailand would have do better to deal with Malaysia's aerial deliveries if they were to make the final.
"The long balls were difficult to handle [in the first leg] so we have to stop them from being able to do that," he added.
"It is surely not an easy match but there is a happy feeling among the players."
The War Elephants are bidding to win the Suzuki Cup for a record fourth time.
