How to disable Spring Security in unit tests class (Spring Boot 2.3.1)

I have three classes of tests, for two of them I need to disable the Spring Security context. The unit test are not performed using MockMvc so I cannot take advantage of @AutoConfigureMockMvc(addFilters = false). Is there a way to disable it in specific classes using annotations or do I need a profile and configure it to ignore the Spring Security context?

EDIT1: test code

@SpringBootTest
@Transactional
class VirtualMachineServiceUnitTests {

    static List<Team> teams;
    static List<VirtualMachine> virtualMachines;
    static List<Configuration> configurations;
    static List<VirtualMachineModel> models;
    static List<Student> students;
    static List<Course> courses;

    @Autowired TeamRepository teamRepository;
    @Autowired VirtualMachineRepository virtualMachineRepository;
    @Autowired ConfigurationRepository configurationRepository;
    @Autowired VirtualMachineModelRepository virtualMachineModelRepository;
    @Autowired StudentRepository studentRepository;
    @Autowired CourseRepository courseRepository;
    @Autowired ModelMapper modelMapper;

    @BeforeAll
    static void beforeAll(@Autowired TeamRepository teamRepository,
                          @Autowired VirtualMachineRepository virtualMachineRepository,
                          @Autowired ConfigurationRepository configurationRepository,
                          @Autowired VirtualMachineModelRepository virtualMachineModelRepository,
                          @Autowired StudentRepository studentRepository,
                          @Autowired CourseRepository courseRepository) {

        // ...

    }

    @Autowired
    VirtualMachineService virtualMachineService;

    @Test
    void createVirtualMachine() {

        // ...

    }
