For angular moments $10$ ($18^\circ$) down to non-linear scales, the results are in agreement with the standard $Łambda$CDM cosmology, with a galaxy bias roughly matching that of the NRAO VLA Sky Survey (NVSS) AGNs. We further explore the redshift dependence of the fraction of radio activity on stellar mass, $f_RL M_*^\alpha_0 + \alpha_1 z$, and find $\alpha_1=2.14\pm0.23$, ruling out a non-evolution hypothesis at the $9\sigma$ confidence level. The results are consistent with the measurements obtained with NVSS AGNs, though considerably more precise thanks to the significantly higher number density of objects in CatWISE2020. The excess dipole and high clustering signal above angular scale $\approx 18^\circ$ remain anomalous.
