Abstract: Quantum synchronization (QS) in open many-body systems offers a promising route for controlling collective quantum dynamics, yet existing manipulation schemes often rely on dissipation engineering, which distorts limit cycles, lacks scalability, and is strongly system-dependent. Here, we propose a universal and scalable method for continuously tuning QS-from maximal synchronization under isotropic interactions to complete synchronization blockade (QSB) under fully anisotropic coupling in spin oscillator networks. Our approach preserves intrinsic limit cycles and applies to both few-body and macroscopic systems. Using two spin-1 oscillators as an example, we analytically show that QS arises solely from spin flip-flop processes and their higher-order correlations, while anisotropic interactions induce nonsynchronizing coherence. However, unlike in finite spin-1 systems, in macroscopic spin networks we find that QSB can occur even when spin flip-flop processes are present. In this regime, anisotropic interactions actively suppress synchronization, demonstrating that the emergence of QSB is not merely a trivial consequence of the absence of synchronizing channels. The proposed mechanism is experimentally feasible using XYZ interactions and optical pumping and provides a general framework for programmable synchronization control in complex quantum networks and dynamical phases of matter.
