This "works" for me:

scene.getStylesheets().add("data:base64," + Base64.getUrlEncoder().encodeToString("""
    .-FX-INTERNAL-header-button-container {
        -fx-background-color: #ff000055;
    }""".getBytes(StandardCharsets.UTF_8)));


It's still not API, and still not a proper use of this feature.
