They're not incompatible in the sense that they assume different physics, but they are very different strategies. The fusion triple product is the go to figure of merit for napkin calculations, it's temperature X confinement time X ion density MCF strategies go in on maximizing confinement time, while ICF jack up temperature and ion density. This particular ICF approach, (if I'm understanding their paper correctly) is going so high on both that they're leaving the thermal regime behind and doing an honest to glob nuclear chain reaction with having the alpha products prompt other boron nuclei to accelerate up to fusion speed causing more reactions, which is pretty exciting.
