A novel non-minimal interaction of neutral right-handed fermion and abeliangauge field in the covariant $\Theta$-exact noncommutative standard model(NCSM) which is invariant under Very Special Relativity (VSR) Lorentz subgroup,opens an avenue to study the top quark pair production at linear colliders.Here the coupling denoted as $\kappa$ and the noncommutative (NC) scale$\Lambda$. In this work, we consider two types of analysis, one is withoutconsidering helicity basis and another, considering helicity states of thepolarized and unpolarized initial and final particles. In the first case, when$\kappa$ is positive and for certain values of $\Lambda$, we arrived a specificthreshold value of machine energy (units of GeV) $\sqrt{s_0}$ ($ \simeq 2.52~\Lambda + 39$ ) may be quite useful to probe NCSM with the unpolarized beam.The statistical $\chi^2$ analysis of the azimuthal anisotropy is quite possiblewhen $\kappa$ takes negative value $0 >\kappa> -0.596$ which persuade a lowerlimit on NC scale $\Lambda$ ($ 1.0\, \text{to} \, 2.4\,\text{TeV}$) at$\kappa_{max}=-0.296 (95\%$ C.L) according to luminosity ranging from$100\,fb^{-1} \text{to}1000\,fb^{-1}$ at machine energy$\sqrt{s}=1.4\,\text{TeV}\,\text{and}\, 3.0\,\text{TeV}$. In another case, weperformed polarized beam analysis to probe NCSM in the light of followingobservables azimuthal anisotropy, helicity correlation, and top quark helicityleft-right asymmetry. The polarization of the initial beam $\{P_{e^{-}},P_{e^{+}}\} = \{-0.8,0.3\}( \{-0.8,0.6\})$ enhances the ranges oflower limit on $\Lambda$, $i.e.\, 1.13 \, \text{to} \, 2.80\,\text{TeV}$ at$\kappa_{max}$ alongside the $\kappa_{max}$ enhanced into $-0.5445 \,(-0.607)$$95\%$C.L accord with luminosity and $\sqrt{s}$. Finally, we studied theintriguing mixing of the UV and the IR by invoking $T(2)$ VSR Lorentz subgroupsymmetry on NC tensor $\Theta_{\mu\nu}$.
