Dynamically change uri() method's value in spring-cloud-gateway

Is it possible to somehow dynamically change the value of the uri() method in spring-cloud-gateway?

I have this method:

    private <T extends RequestData> Function<PredicateSpec, Route.AsyncBuilder> walletRoute(String server, String path, String method, Class<T> inClass) {
    return r -> r.path(path)
                 .and().method(method)
                 .and().readBody(inClass, requestBody ->
                    findWalletInstanceWithUserRef(requestBody.getPlayerExternalReference()).equals(server))
                 .uri("http://" + server).id("th");
}

This method call returns the hostname I want to put inside uri():

findWalletInstanceWithUserRef(requestBody.getPlayerExternalReference())

Is it somehow possible to do that?

Thank you
