2020 duramax break in procedures

what are the proper break in procedures for these diesels..i did find some info in the owners manual but do not know if it is for gas or diesel...yes i read the diesel supplement and spent most of last night going over the owners manual. my guy from the dealership said just drive it normal. well i tow my 24 foot enclosed trailers every week hundreds of miles so want to make sure i bring it into the working world properly. i picked it up with 44 miles on it an now it has 181.
