In this paper, we investigate the detectability of secondary spin in theextreme mass ratio inspirals system within a modified gravity model coupledwith a scalar field. The central black hole, which reduces to a Kerr one, iscircularly spiralled by a scalar-charged spinning secondary body on theequatorial plane. The analysis reveals that the presence of the scalar fieldamplifies the secondary spin effect, allowing for a lower limit of thedetectability and an improved resolution of the secondary spin when the scalarcharge is sufficiently large. Our findings suggest that the secondary spindetection is more feasible when the primary mass is not large, and TianQin isthe optimal choice for detection.
