In this paper we have studied the phenomenon of non-standard interaction mediated by a scalar field (SNSI) in the context of P2SO experiment and compared its sensitivity with DUNE. In particular, we have studied the capability of these two experiments to put bounds on the diagonal SNSI parameters i.e., $η_{ee}$, $η_{μμ}$ and $η_{ττ}$ and studied the impact of these parameters on the determination of neutrino mass ordering, octant of $θ_{23}$ and CP violation (CPV). In our analysis we find that, the parameter $Δm^2_{31}$ has a non-trivial role if one wants estimate the bounds on $η_{μμ}$ and $η_{ττ}$ assuming SNSI does not exist in nature. Our results show that sensitivity of P2SO and DUNE to constraint $η_{μμ}$ and $η_{ττ}$ are similar whereas the sensitivity of DUNE is slightly better for $η_{ee}$. We find that the mass ordering and CPV sensitivities are mostly affected by $η_{ee}$ compared to $η_{μμ}$ and $η_{ττ}$ if one assumes SNSI exists in nature. On the other hand, octant sensitivity is mostly ... : 24 pages, 15 figures, 4 tables, Includes analytical expression for appearance channel probability ...
