no M5-Core to try
https://github.com/m5stack/M5Tough/blob/master/src/M5Display.h

class M5Display : public TFT_eSPI {
    public:
      static M5Display* instance;
      M5Display();
      void begin();
      void sleep();
      void wakeup();
      void setBrightness(uint8_t brightness);
      void clearDisplay(uint32_t color=ILI9341_BLACK) { fillScreen(color); }
      void clear(uint32_t color=ILI9341_BLACK) { fillScreen(color); }
      void display() {}

so you can try this

#include <M5Display.h>

M5.Lcd.setBrightness(value);    //uint8_t  Brightness (0: Off - 255:Full)

1.M5Stack.Lcd use Brightness (0: Off - 255:Full)

// ########################################################
// Section 2. Define the pins that are used to interface with the display here
//#######################################################

// If a backlight control signal is available then define the TFT_BL pin in Section 2
// below. The backlight will be turned ON when tft.begin() is called, but the library
// needs to know if the LEDs are ON with the pin HIGH or LOW. If the LEDs are to be
// driven with a PWM signal or turned OFF/ON then this must be handled by the user
// sketch. e.g. with digitalWrite(TFT_BL, LOW);

#define TFT_BL   32            // LED back-light control pin
#define TFT_BACKLIGHT_ON HIGH  // Level to turn ON back-light (HIGH or LOW)
