Tuchel could become only the fourth manager to reach a World Cup final with a team other than their home nation - and first since Austrian Ernst Happel with the Netherlands in 1978.
But his England side will have their work cut out against Argentina, who are in the World Cup's last four for the third time in the past four editions.
When asked by BBC Sport's Sami Mokbel if the rivalry between the two sides would provide extra motivation on Wednesday, Tuchel said: "We don't use it as fuel. We know why we're here - we know what we want.
"We were never shy of expecting that from us, of saying it, of dreaming it. We're in the semi-final - we arrive very hungry and want the next win."
Political tensions, especially around the Falklands War in the 1980s, have dominated the relationship between the two nations.
After Argentina's 3-2 win over Egypt in the last 16, their players were filmed singing a chant referencing the islands.
But Tuchel said: "We respect our opponent, but we don't dip into historic events. We don't make it bigger than it is.
"It is a big football match and a big occasion. We are very excited and grateful, but very hungry and ready to go.
"It's a big rivalry and it's two big football nations who love football."
The semi-final will also be the first time England will face Argentina great Lionel Messi on the international stage.
"How he carries the team is absolutely incredible - there are no words," said Tuchel when asked about the Argentina captain.
"In this tournament he is just the leader, and the key player in any team he plays.
"When Messi has the ball, the movement starts. The technical delivery of Messi is on the highest level. There is a lot to take care of, but we are here to play our way in the semi-final. We are here to impose our style, our strengths.
"A lot of coaches have tried [to stop Messi]. He seems to always have another gear and another solution. He's unique. We know his quality.
"We know how big the obstacle is. We know how big the ask is."
Tuchel also spoke about how he likes to try to unwind during what has been a long summer camp.
"Sometimes you just go on a bike, and you need a big parking lot and an ice cream in your hand," he said.
"For 15 minutes, you feel like 15 years old. 15 not 50! You enjoy your evening in a warm summer for 15 minutes with an ice cream, and you reconnect to that beauty of that feeling which we all have inside of us."
