The Carlin driver, who took podiums in both races in the F2 season opener in Bahrain, says he is more at ease sticking to one car than he was last year.
In 2021, Lawson competed in the DTM for Red Bull AF Corse alongside Williams Formula 1 driver Alex Albon, with the pair finishing second overall.
But he will solely focus on F2 this year, having moved to Carlin from Hitech Grand Prix, who he finished ninth with last year.
Speaking after taking second place in the feature race on Sunday, Lawson said he felt he would “for sure” benefit from only racing in one series.
“I’m very grateful to have had the opportunity to race in DTM last year, I think honestly I learned a lot doing it,” he said.
“But obviously doing a season of Formula 2 as well was quite tough changing between the cars, so this year it’s nice to be able to focus just on the one.
“Obviously we spoke yesterday about the format change, I think that helps as well, a lot more racing for us.
“I’m definitely more comfortable and will be more comfortable every round staying in the same car.”
Lawson said in October that he no longer wished to remain in DTM after a controversial season finale denied him the chance to win the title, having become an innocent victim to an opening lap collision triggered by his championship rival Kelvin van der Linde.
With his Ferrari suffering severe suspension damage and lapping at the rear of the field, the Kiwi helplessly watched on as Maximilian Gotz snatched the title from his grasp with the help of team orders from Mercedes.
An emotional Lawson lashed out at van der Linde in the immediate aftermath of the race, calling him an “idiot” and the “dirtiest driver he’s raced against” for crashing into him twice during the final round.
Despite receiving an apology from van der Linde, Lawson said he thoroughly enjoyed his campaign, but the events at Norisring left him with a sour taste in the mouth about the quality of racing in the championship.
