We examine the accretion process in a thin disk surrounding a supermassive black hole within the framework of Einstein–Maxwell-scalar (EMS) gravity. Our investigation aims to elucidate how variations in model parameters affect different physical properties of the disk. When keeping EMS parameters 
and q constant, we observe a reduction in radiation flux and temperature as 
increases. However, the luminosity and radiative efficiency exhibit relatively minor variation. Conversely, under fixed and q, an escalation in leads to heightened levels of radiation flux, temperature, luminosity, and radiative efficiency. These results underscore the diverse influences of model parameters on observable metrics, providing valuable insights for the astronomical study of distinct black holes.
