This is possible, though how to do it is component-specific. However, I'm not sure how much benefit you'll get: CAM and POP together make up most of the total output volume.
You can turn off CLM history output by putting the following in user_nl_clm:
For MOSART (runoff), you could either add individual fields to the list rtmhist_fexcl1 in user_nl_mosart, or you could set rtmhist_nhtfrq to some large negative number in user_nl_mosart (e.g., -8760 means only write history files every 8760 hours, i.e., every year; -87600 means every 10 years; etc.).
For CISM (ice sheet), you could put the following in user_nl_cism to get history output only every 100 years, for example:
I am less familiar with CICE and WW3, but it looks like you could use similar mechanisms: see variables starting with 'hist' here CESM2 Series Public Release and outfreq here CESM2 Series Public Release (it looks like outfreq = 0 should do what you want for ww3).
