Domain walls (DWs) from spontaneously breaking of the discrete symmetry inapproximate $Z_3$-invariant NMSSM can collapse and lead to the stochasticgravitational waves (GWs) background signals observed by PTA collaborationswith the presence of some explicitly $Z_3$ breaking terms in the NMSSMeffective superpotential and scalar potential. In the presence of a hiddensector, such terms may origin from the geometric superconformal breaking withholomorphic quadratic correction to frame function when the globalscale-invariant superpotential is naturally embedded into the canonicalsuperconformal supergravity models. The smallness of such mass parameters inthe NMSSM may be traced back to the original superconformal invariance. Naiveestimations indicate that SUSY explanation to muon $g-2$ anomaly can havetension with the constraints on SUSY by PTA data, because large SUSYcontributions to $\Delta a_\mu$ in general needs relatively light superpartnerswhile present $\Omega_{gw}^0$ can set the lower bounds for $m_{soft}$. Wecalculate numerically the signatures of GWs produced from the collapse of DWsand find that the observed nHZ stochastic GWs background by NANOGrav etc canindeed be explained with proper tiny values of $\chi m_{3/2}\sim 10^{-14}{\rmeV}$ for $\chi S^2$ case (and $\chi m_{3/2}\sim 10^{-10}{\rm eV}$ for $\chi H_uH_d$ case), respectively. Besides, there are still some parameter points, whoseGWs spectra intersect with the NANOGrav signal region, can explain the muon$g-2$ anomaly to $1\sigma$ range.
