Ferrite beads have little inductance and at low frequencies <100kHz they don't do much.
You can get some multi-turn ferrite beads, but you need more inductance, 10uH-1mH.
I would add an LC lowpass filter with a resistor across the inductor to dampen it. Don't chose values near the 62.5kHz or its harmonics to avoid resonance.
I have also used 1mH common-mode chokes on 24V vehicles, depending on the load current and the noise source, and if things don't need a direct ground.
