Is there any way to toggle Rest template to use Basic Auth or OAuth token?

Question

My Service A makes a GET call to Service B, to get some details. In my code, I've configured below that builds RestTemplate with Basic Auth creds.

@Bean(name=Bobresttemplate)
public RestTemplate resttemplate(RestTemplateBuilder restTemplateBuilder) {
        this.restTemplate = restTemplateBuilder
                .basicAuthentication("username", "password")
                .build();
    }

I use this in my RestClient.Java/ @Service classes by Autowiring.

@Autowired
@Qualifier("Bobresttemplate")
RestTemplate restTemplate;

My Question: I'm building Bobresttemplate with Basic Auth, now if I want to use this same Rest template but instead of Basic Auth, I want to use OAuth token to call 3rd party service.I want to acheive a functionality where based on a Toggle, I can use this same BobRestTemplate but with either of Basic Auth or OAuth.

What extra config do I need to do? Do I need to create another Bean and build this RestTemplate with OAuth creds?

I'm looking to understand whether do I need to create another Bean for configuring this template? Or can I use Interceptors?

It may be helpfull to use spring.profiles feature:

@Profile("basic-auth")
@Bean(name="Bobresttemplate")
public RestTemplate resttemplateBasic(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder
            .basicAuthentication("username", "password")
            .build();
}

@Profile("jwt")
@Bean(name="Bobresttemplate")
public RestTemplate resttemplateJwt(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder
            ...
            .build();
}

so in config you just enable profile that you need (no changes in place of injecting resttemplate bean):

spring.profiles.active=jwt

or

spring.profiles.active=basic-auth
