Spring AOP change value of methods argument on around advice

Question

Is it possible to change method argument value on basis of some check before executing using Spring AOP

My method

public String doSomething(final String someText, final boolean doTask) {
    // Some Content
    return "Some Text";
}

Advice method

public Object invoke(final MethodInvocation methodInvocation) throws Throwable {
    String methodName = methodInvocation.getMethod().getName();

    Object[] arguments = methodInvocation.getArguments();
    if (arguments.length >= 2) {
        if (arguments[0] instanceof String) {
            String content = (String) arguments[0];
            if(content.equalsIgnoreCase("A")) {
                // Set my second argument as false
            } else {
                // Set my second argument as true
            }
        }
    }
    return methodInvocation.proceed();
}

Please suggest me the way to set the method argument value as there is no setter options for the argument.

I got my answer using MethodInvocation

public Object invoke(final MethodInvocation methodInvocation) throws Throwable {
    String methodName = methodInvocation.getMethod().getName();

    Object[] arguments = methodInvocation.getArguments();
    if (arguments.length >= 2) {
        if (arguments[0] instanceof String) {
            String content = (String) arguments[0];
            if(content.equalsIgnoreCase("A")) {
                if (methodInvocation instanceof ReflectiveMethodInvocation) {
                    ReflectiveMethodInvocation invocation = (ReflectiveMethodInvocation) methodInvocation;
                    arguments[1] = false;
                    invocation.setArguments(arguments);
                }
            } else {
                if (methodInvocation instanceof ReflectiveMethodInvocation) {
                    ReflectiveMethodInvocation invocation = (ReflectiveMethodInvocation) methodInvocation;
                    arguments[1] = true;
                    invocation.setArguments(arguments);
                }
            }
        }
    }
    return methodInvocation.proceed();
}
