Problems w/ Osepp TB6612 Shield n Arduino R4 in with H-Bridge of DC Motors

I'm trying to power 4 different 25mm DC Motors. Ive tried multiple adafruit Libraries and associated tutorials and can get the motors to run in one direction at a speed using various setspeed and pwm library functions. Any command for releasing or changing direction of the motors doesn't work with either the Adafruit Motor Library Version 1 or Version 2 or the Adafruit Shield master library. I would love to know simply what pins I can use to control the H-bridge for each of the 4 motors and bypass the libraries but I can't figure it out from the schematics.

Here is Motor Shield schematic.

Here is some sample modified code from adafruit examples:

This is attempt using Adafruit V1 Library "AFMotor.H"

#include <AFMotor.h>

AF_DCMotor motorFL(1);

void setup() {
  Serial.begin(9600);        
  
  motorFL.setSpeed(0);
  motorFL.run(RELEASE);
}
void loop() {
      motorFL.run(RELEASE);
      motorFL.run(BACKWARD);
      motorFL.setSpeed(50);
      delay(1000);  
      motorFL.run(RELEASE);
      motorFL.run(FORWARD);
      delay(1000);  
      motorFL.run(RELEASE);
      motorFL.run(BACKWARD);
      delay(1000);  
      motorFL.run(RELEASE);   

}

This coding results in the correct motor(1-4) moving at a certain direction at the setSpeed command speed.
Next i tried the Adafruit V2 library "Adafruit_MotorShield"

#include <Wire.h>
#include <Adafruit_MotorShield.h>


Adafruit_MotorShield AFMS = Adafruit_MotorShield(); 

Adafruit_DCMotor *myMotor = AFMS.getMotor(1);

void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Adafruit Motorshield v2 - DC Motor test!");

  AFMS.begin();  // create with the default frequency 1.6KHz

  myMotor->setSpeed(0);
  myMotor->run(FORWARD);
  myMotor->run(RELEASE);
}

void loop() {
    myMotor->run(FORWARD);
    myMotor->setSpeed(100);  
    delay(1000);
    myMotor->run(RELEASE);
    myMotor->run(FORWARD);
    delay(1000);
    myMotor->setSpeed(100);  
    myMotor->run(FORWARD);  
    delay(1000);
    myMotor->run(RELEASE);
    myMotor->run(FORWARD);
    delay(1000);  
 }

The V2 code does nothing for my motors.

Ive dug into the libraries and cant find any tutorials regarding specifically how to set up H-Bridge or PWM speed control of each individual motor. I'm sure the schematic has something on it to help but I cant find it. If somebody could find and explain a command for setting the InA/B or EnA/B of the H-bridge that would be wonderful.

You're using the Adafruit library, do you have an Adafruit motor shield? Post a diagram showing which Arduino pin goes to which motor shield pin and the power connections.
