VL53L5CX multi-sensor ranging reading must be delayed?

I used X-NUCLEO-53L5A1 + 2 VL53L5CX-SATEL, and the data read output speed has a delay in the code: HAL_Delay(POLLING PERIOD), POLLING PERIOD == 1s, and then I want to quickly, so I canceled HAL_Delay() (Picture1), But it took a long time to check (Pi...
