In 2020, Herbst assumed full-time driving duties in the No. 18. He qualified for the playoffs but was eliminated following the first round. He ended the year with a twelfth place points finish, four top-five finishes, seventeen top tens, and the best finish of second at Auto Club Speedway and Kentucky Speedway. After the season, JGR signed Daniel Hemric to drive the No. 18 full-time starting in 2021, leaving Herbst without a ride.

On December 10, 2020, Stewart–Haas Racing announced Herbst would drive the No. 98 Ford beginning with the 2021 season. After a rough start to the season that saw his involvement in wrecks—none of which were of his doing—in three of the first four races, he rebounded with a fourth-place finish at Phoenix Raceway. In 2022, Herbst would have his best season in his Xfinity career; his eight top-fives and twenty top-ten finishes during the season were all career-highs.

Herbst began the 2023 season with a sixth-place finish at Daytona. He then scored five more consecutive top-ten finishes. Despite missing the playoffs, Herbst scored his first career win at Las Vegas. The end to his season was strong, as the win was part of a five-race streak of top-five finishes.

Remaining at SHR for 2024, Herbst repeated the previous year's result to finish sixth at Daytona. Having run in the top positions throughout the following race at Atlanta, he ran out of fuel whilst sitting second with a few laps left, eventually dropping to 15th. Herbst scored his first win of the season at Indianapolis after he made a spectacular last lap pass on Aric Almirola. Unfortunately, he would be knocked out of the first round of the playoffs. At Phoenix, Herbst gave Stewart–Haas Racing its final race win; he finished seventh in the points standings.

On May 28, 2024, Stewart–Haas Racing announced it would shut down its NASCAR operations at the end of the season.

On October 12, 2019, Herbst was passing Johnny Sauter on the final lap for the win in the tri-oval at Talladega Superspeedway but was blocked across the apron forcing NASCAR to penalize Sauter and give Spencer Boyd his first career win, Herbst would finish third.

Herbst returned to the Truck Series in February 2021 for the Daytona road course race, driving the No. 17 Ford for David Gilliland Racing. He returned to the No. 17 truck for Daytona and Kansas in 2022.

Herbst signed with Rick Ware for the 2024 Daytona 500 driving the No. 15 again but this time with Monster Energy as a sponsor instead of SunnyD, which was his sponsor in the previous year's race. Herbst qualified in twelfth but finished in twentieth in the Duels, which started him in 36th for the race. Herbst was at one point in the top-ten during the race but ultimately finished in 24th. Herbst ran another race that same year in the No. 15 at Kansas, starting 37th and finishing 35th, two laps down. Herbst ran two more races for Rick Ware at Nashville and Richmond finishing 37th and 33rd.

On November 20, 2024, 23XI Racing announced that Herbst would drive the No. 35 Toyota full-time for the 2025 season. Herbst will run long-time partner Monster Energy as his sponsor. He started the season with a seventeenth-place at the 2025 Daytona 500. Herbst struggled throughout the season, failing to score a single top-ten finish and only finishing inside the top-twenty eight times with a best finish of fourteenth at Texas, and finished 35th in the final standings. Shortly after the Charlotte Roval race, the No. 35 car was disqualified for failing post-race height inspection.
