If dark matter is uniformly dispersed and interacts only gravitationally, then the following proposal is of no consequence.
However, if dark matter isn't uniformly dispersed, and is instead particulated (such as in the form of numerous small black holes), then we might be able to measure the passage of one of these black holes, should one of them come our way.
It would not be difficult to build a 3D device to measure the local warping of space-time that would reveal a passing small black hole. Even precise measurements of the orbits of the planets would reveal this, albeit in retrospect.
Over time, if no such variations in movement exist, then it's likely that dark matter is very distant, that it is evenly disbursed, or that there's something amiss in our current understanding of the space-time continuum which raises a false assumption that dark matter might exist in the first place.
