description: This Letter reports a search for charge-parity ($CP$) symmetry violating nonstandard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from $ν_μ(\barν_μ)\rightarrowν_μ(\barν_μ)$ and $ν_μ(\barν_μ)\rightarrowν_{e}(\barν_{e})$ oscillation channels are used to measure the effect of the NSI parameters $\varepsilon_{eμ}$ and $\varepsilon_{eτ}$. With 90% CL the magnitudes of the NSI couplings are constrained to be $|\varepsilon_{eμ}| \, \lesssim 0.3$ and $|\varepsilon_{eτ}| \, \lesssim 0.4$. A degeneracy at $|\varepsilon_{eτ}| \, \approx 1.8$ is reported, and we observe that the presence of NSI limits sensitivity to the standard $CP$ phase $δ_{\tiny\text{CP}}$.
