Carbon gravel bikes are positively warty with mounts, though they do favor bikepacking setups in the front over something like a decaleur. In the rear there are the usual mounts for the lower rack stays; sometimes the upper stays need to go to a seat collar.
The aluminum Domane in the OP has normal upper and lower rack mounts. The carbon one has mounts hidden on the underside of the stays, and a compartment in the down tube.
