• The FF terms only affect the fakes_sm process
• The other terms (e.g. FSR, renorm, ...) affect every process but fakes_sm

Something like this might be the minimal changes needed:

                        check_zero_arr0 = check_zero_arr0 and ('fakes' in proc and 'FF' in syst) or ('fakes' not in proc and 'FF' not in syst)
                        check_zero_arr1 = check_zero_arr1 and ('fakes' in proc and 'FF' in syst) or ('fakes' not in proc and 'FF' not in syst)
                        if "Up" in syst:

Now I don't think proc is defined here, so see if there's an easy way to pass it or get it here.
