  Consideration of extra spatial dimensions is motivated by the unification of
gravity with other interactions, the achievement of the ultimate framework of
quantum gravity, and fundamental problems in particle physics and cosmology.
Much attention has been focused on the effect of these extra dimensions on the
modified theories of gravity. Analytically examining astrophysical phenomena
like black hole shadows is one approach to understand how extra dimensions
would affect the modified gravitational theories. The purpose of this study is
to derive a higher dimensional metric for a dark compact object in STVG theory
and then examine the behavior of the shadow shapes for this solution in STVG
theory in higher dimensions. We apply the Carter method to formulate the
geodesic equations and the Hamilton Jacobi method to find photon orbits around
this higher dimensional MOG dark compact object. We investigate the effects of
extra dimensions and the STVG parameter alpha on the black hole shadow size.
Next, we compare the shadow radius of this higher dimensional MOG dark compact
object to the shadow size of the supermassive black hole M87, which has been
realized by the Event Horizon Telescope (EHT) collaborations, in order to
restrict these parameters. We find that extra dimensions in the STVG theory
typically lead to a reduction in the shadow size of the higher dimensional MOG
dark compact object, whereas the effect of parameter alpha on this black hole
shadow is suppressible. Remarkably, given the constraints from EHT
observations, we find that the shadow size of the four dimensional MOG dark
compact object lies in the confidence levels of the EHT data. Finally, we
investigate the issue of acceleration bounds in higher dimensional MOG dark
compact object in confrontation with EHT data of M87.
