We demonstrate reduction of the dc polarizability Cesium atom Rydberg states in a 77 K environment utilizing microwave field dressing. In particular we reduce $52P_{3/2}$ which have resonances at 5.35 GHz to $51D_{5/2}$, suitable for interfacing atoms superconducting resonators cryogenic environment. measure using Magneto-Optical-Trap (MOT) loss spectroscopy. Using an off-resonant radio-frequency (RF) dressing coupling and $51D_{5/2}$ $ 52P_{3/2}$ over 80$\%$. Experimental findings are good agreement with numerical model atom-dressing system developed Shirley-Floquet formalism. also that is highly anisotropic, near total nulling possible when fields aligned, but only factor two orthogonal. These results may aid stabilizing against varying present surfaces, enabling advancement development hybrid - resonator quantum gates.
