A large amount of data on hadronic two body weak decays of anti-tripletcharmed baryons $T_{c\bar 3}$ to an octet baryon $T_8$ and an octet or singletpseudoscalar meson $P$, $T_{c \bar 3} \to T_8 P$, have been measured. The SU(3)flavor symmetry has been applied to study these decays to obtain insights aboutweak interactions for charm physics. However not all such decays needed todetermine the SU(3) irreducible amplitudes have been measured forbidding acomplete global analysis. Previously, it has been shown that data from measureddecays can be used to do a global fit to determine all except one parityviolating and one parity conserving amplitudes of the relevant SU(3)irreducible amplitudes causing 8 hadronic two body weak decay channelsinvolving $\Xi^0_c$ to $\eta$ or $\eta'$ transitions undetermined. It isimportant to obtain information about these decays in order to guideexperimental searches. In this work using newly measured decay modes by BESIIIand Belle in 2022, we carry out a global analysis and parameterize the unknownamplitudes to provide the ranges for the branching ratios of the 8 undetermineddecays. Our results indicate that the SU(3) flavor symmetry can explain themeasured data exceptionally well, with a remarkable minimal $\chi^2/d.o.f.$ of1.21 and predict 80 observables in 45 decays for future experimental data totest. We then vary the unknown SU(3) amplitudes to obtain the allowed range ofbranching ratios for the 8 undetermined decays. We find that some of them arewithin reach of near future experimental capabilities. We urge our experimentalcolleagues to carry out related searches.
