How to remove a filter from spring security?

In Spring Security 4.0 there is so called Default Login Page which looks like the following:

Dug a bit into the source code I found the Filter org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter

which renders that login page. Actually, it has private String generateLoginPageHtml(HttpServletRequest request, boolean loginError, boolean logoutSuccess) method, which contains the following code snippet:

if (formLoginEnabled) {
    sb.append("<h3>Login with Username and Password</h3>");
    sb.append("<form name='f' action='").append(request.getContextPath()).append(authenticationUrl).append("' method='POST'>\n");
    sb.append(" <table>\n");
    sb.append("    <tr><td>User:</td><td><input type='text' name='");
    sb.append(usernameParameter).append("' value='").append("'></td></tr>\n");
    sb.append("    <tr><td>Password:</td><td><input type='password' name='").append(passwordParameter).append("'/></td></tr>\n");

    if (rememberMeParameter != null) {
        sb.append("    <tr><td><input type='checkbox' name='").append(rememberMeParameter).append("'/></td><td>Remember me on this computer.</td></tr>\n");
    }

    sb.append("    <tr><td colspan='2'><input name=\"submit\" type=\"submit\" value=\"Login\"/></td></tr>\n");
    renderHiddenInputs(sb, request);
    sb.append("  </table>\n");
    sb.append("</form>");
}

The issue is I want to remove that filter from the filter chain in order to customize my login page, located by the http://my-domain/login url. Is it possible?

My security-config:

<http auto-config="true">
    <intercept-url pattern="/admin**" 
                    access="hasRole('ROLE_USER')" />
    <form-login login-page="/login" 
                default-target-url="/admin" 
                authentication-failure-url="/login?error=true" 
                username-parameter="user"
                password-parameter="password" 
                login-processing-url="/login"/>
    <logout logout-success-url="/login?logout" logout-url="/logout" />
</http>
