The present article contains the study of $D$-homothetically deformed $f$-Kenmotsu manifolds. Some fundamental results on the deformed spaces have been deduced. Some basic properties of the Riemannian metric as an inner product on both the original and deformed spaces have been established. Finally, applying the obtained results, soliton functions, Ricci curvatures and scalar curvatures of almost Riemann solitons with several kinds of potential vector fields on the deformed spaces have been characterized.

Keywords: $f$-Kenmotsu manifolds, $D$-homothetically deformed $f$-Kenmotsu manifolds, almost Riemann solitons, gradient almost Riemann solitons
