Rotate cubetexture in Three.js

I got this cubetexture in Three.js. Say I want to rotate the cubeTexture itself 180 degrees. I know I can do this by rotating the camera but I want to rotate the texture itself and not the camera. How can I achieve this?

I want to rotate the x axis of the cubeTexture causing it to display the opposite side. Something like texture.flipX = true; would be handy.

var camera, scene, box, renderer;

init();
animate();

function init() {

    renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    scene = new THREE.Scene();

	const texture = new THREE.CubeTextureLoader()
		.setCrossOrigin('')		.setPath('https://alca.tv/static/codepen/pens/common/SwedishRoyalCastle/').load(['px.jpg', 'nx.jpg', 'py.jpg', 'ny.jpg', 'pz.jpg', 'nz.jpg']);
	
    scene.background = texture;

    const geometry = new THREE.BoxGeometry(1, 1, 1);
    const material = new THREE.MeshBasicMaterial({ color: new THREE.Color('skyblue') });
    box = new THREE.Mesh(geometry, material);
    scene.add(box);
    
    camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    camera.position.z = 5;
    scene.add(camera);
    document.body.appendChild(renderer.domElement);
}

function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}

Rotating cube textures is not yet supported. Read the following issues for more details:
