Truck throwing P2459 code

[Cfish94]

Just bought a used 2020 Ram 2500 with 40k miles on it 4 days ago. Engine light came on. Went and got the code read and it’s P2459 (DPF regeneration frequency)

I have been searching the internet trying to find a fix or any info in general and havent had much luck...

I’m calling the dealership in the morning but with it being used I doubt they will be much (free) help.
Any thoughts or suggestions?!
