Striker Holt scored a stoppage-time winner against Everton last weekend to earn Norwich their first win in 10 Premier League games and an eight-point cushion above the drop zone.
The 31-year-old netted only his fifth goal of season in a 4-4-2 formation after being deployed for the most part as a lone striker, but should boss Chris Hughton revert to 4-4-1-1 against leaders Manchester United, Holt will comply.
"The manager has been open enough to tell everyone that he doesn't expect me to score as many goals as I did last season and I am there to do a job for the team, so you have got to bite your lip and get on with it," Holt said.
"You can never truly say you are happy with that position because obviously you want to score goals, but there is a job to be done and at the moment he thinks I am the best person to do that job.
"You have to adapt to situations. If he goes with the 4-4-1-1 again this week, you have got to get on with it."
Norwich beat United 1-0 at Carrow Road in November but Holt expects a far sterner test at Old Trafford.
"It is one of the biggest challenges," he added.
"But if you look at our record, we do not too badly at the so-called bigger clubs.
"We can only do what we do best, go up there with a plan, stick to that and see where it takes us."
