According to the cam 6.3 docs it is the grid that sets which dynamical core will be used in CAM:
"These grid configurations determine which dynamical core will be used in CAM as well as the spatial resolution of the grids for each component model participating in the compset. CAM currently supports the Finite Volume (FV), Spectral Element (SE), and Eulerian (EUL) dynamical cores. This release adds developmental support for NOAA’s Finite Volume Cubed Sphere (FV3) dynamical core. The grid name is usually given in a shortened form called an alias which lists the grids used by the atmosphere, land, and ocean/ice components. CAM grid names begin with a letter or two denoting the dynamical core followed by a string of digits representing the grid resolution. The Finite Volume Grids begin with the letter ‘f’, SE grid names begin with ‘ne’, Eulerian grids begin with ‘T’, and FV3 grid names begin with the letter ‘C’."
DART can only be used if the grid is FV (f grids) or SE (ne grids)
select dart cam-fv or dart cam-fv based on CAM_DYCORE or maybe grid.
assuming CAM_DYCORE is set when you set up the case.
