However, existing approaches either offer high lateral precision without independent reaction tuning or provide energetic control at the expense of spatial confinement. Herein, we introduce a photoelectrochemical\u2010driven strategy that combines the spatially resolved laser activation of precursors with electrochemical reaction gating that allows for modulation of the electron\u2010transfer driving force. Within a defined potential window, the degree of covalent addend binding on graphene can be continuously tuned by varying the applied bias under otherwise identical irradiation conditions. The electrochemical potential serves as an independent control parameter, complementing laser power and irradiation time, and thus provides an additional tool for the calibration of the degree of functionalization. Negative potentials enhance the covalent addend binding, whereas positive potentials suppress the reaction. This allows for a reproducible switching between active and inactive states. The electrochemically defined \u201coff\u201d condition enables in situ Raman characterization in the presence of the precursor solution without inducing unintended additional addend binding, enabling uninterrupted, stepwise monitoring of the functionalization process. This combination of laser\u2010pathway guided spatially resolved patterning and voltage\u2010controlled reaction tuning establishes a dual\u2010control platform for future precision graphene
