How to disable @PreAuthorize annotation that is set on method level, in case I permit all requests globally on given end point?

I have this security configuration:

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class SecurityConfigurer extends WebSecurityConfigurerAdapter {

    // @formatter:off
    @Override
    public void configure(final HttpSecurity http) throws Exception {
        http.headers().frameOptions().disable()
            .and()
        .csrf().disable()
        .authorizeRequests()
            .antMatchers("/api/test/**").authenticated()
            .antMatchers("/**").permitAll()
        .and()
        .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

And this controller:

@RestController
public class MyController {

    @GetMapping("")
    @PreAuthorize("hasRole('ROLE_USER')")
    public String hello() {
        return "Hello world!";
    }

    @GetMapping("/api/test")
    @PreAuthorize("hasRole('ROLE_ADMIN')")
    public String helloTest(Principal principal) {
        System.out.println(principal.toString());
        return "Hello test world!";
    }
}

Both controller methods have a @PreAuthorize annotation. In security configuration I require the /api/test/** endpoints to be secured, while the rest should be available as anonymous.

However when I test given controller, while opening http://localhost:8080 I get 401 Unauthorized because of the @PreAuthorize("hasRole('ROLE_USER')") annotation while I want it unsecured (.antMatchers("/**").permitAll()).

TL:DR - I want the "global" configuration overwrite the @PreAuthorize() annotation.

Why? Because I want to set the .antMatchers("/api/test/**").authenticated() part from the application.properties file so it can happen that if I change the value to "/api/test/hello/**" then I want the helloTest method be available for anonymous users without going through all the controllers and removing the @PreAuthorize() annotation everywhere and hope that I found it all. Thanks in advance.
