We theoretically design a hybrid nanomechanical resonator (NR) system composed of a quantum dot (QD) embedded between two doubly clamped suspended NRs. The QD is driven by two-tone fields, while the NRs are coupled via phase-dependent phonon–phonon interactions. By examining the absorption spectrum under different exciton-pump detuning conditions with a weak probe field, we observe distinct phenomena in resonant and off-resonant regimes. On resonance, the coupling strength between the two NRs can be directly extracted from spectral splitting. Off resonance, the system exhibits phonon-induced transparency with two tunable windows, whose positions and depths are governed by the NR interactions, frequencies, and pump detuning. Crucially, phase modulation enables dynamic switching between single and double transparency windows in this off-resonant regime. Specifically, at 
, destructive interference between NR 1 and NR 2 suppresses one window, whereas at 
, constructive interference splits the spectrum into two transparent bands. This control, achievable via voltage or optical tuning, highlights the potential of system for reconfigurable optical filters and multiplexed quantum memories in integrated quantum platforms.
