I am using STM32G491REI6 Microcontroller. Can we connect Microcontroller ground to the earth to avoid EMI??

MCU ground should be your MCU power supply ground, else EMI will be the least of your problems.

If you describe the power source, packaging design and EMI source, you might get a better response.
