open the board.h file from format with a code editor like visual studio code. Then navigate to the board.h file and copy and paste this

#elif defined(ARDUINO\_UNOWIFIR4)  
#define TOTAL\_ANALOG\_PINS 6  
#define TOTAL\_PINS 20 // 14 digital + 6 analog  
#define VERSION\_BLINK\_PIN 13 // or any available pin for LED  
#define IS\_PIN\_DIGITAL(p) ((p) \>= 0 && (p) \<= 13) // Adjusted for digital pins  
#define IS\_PIN\_ANALOG(p) ((p) \>= 14 && (p) \<= 19) // Adjusted for analog pins  
#define IS\_PIN\_PWM(p) (((p) == 3) || ((p) \>= 5 && (p) \<= 9) || ((p) \>= 10 && (p) \<= 13)) // Adjusted for PWM pins
