A suppression module, a suppression assembly, and a drilling tool are disclosed. The suppression module includes a spindle having a first end and a second end, an ear plate slideably disposed between the first end and the second end, a spring positioned between the ear plate and the first end, and an activation mechanism coaxially disposed around the second end of the spindle. The activation mechanism engages the ear plate, activating the spring, or disengages the ear plate, deactivating the spring. The suppression assembly includes at least two suppression modules in series coupled to a processor. The suppression modules are activated or deactivated by the processor, each of the suppression modules being activated or deactivated independent of the other suppression modules. The drilling tool includes a drill pipe, a drill bit, a vibration sensor, and a suppression assembly between the drill pipe and the drill bit.
