Preventing YouTube caching in browser

Preventing YouTube from being cached in the browser until the image is clicked.

How would I be able to do this, because I can’t figure it out.

It’s the " player_api " that’s still being caught in the browser. How would I be able to prevent that until the image is clicked?

Html:

<script type="text/javascript" src="https://www.youtube.com/player_api"></script>

Javascript:

    "use strict";
    const hide = (el) => el.classList.add("hide");

    function coverClickHandler(evt) {
        const cover = evt.currentTarget;
        hide(cover);
    }
    const cover = document.querySelector(".jacketc");
    cover.addEventListener("click", coverClickHandler);
}());
const videoPlayer = (function makeVideoPlayer() {
    "use strict";

    function onPlayerReady(event) {
        const player = event.target;
        player.setVolume(50); // percent
    }

    function onPlayerStateChange(event) {
        const player = event.target;
        const playerVars = player.b.b.playerVars;
        if (playerVars.loop && event.data === YT.PlayerState.ENDED) {
            player.seekTo(playerVars.start);
        }
    }

    function addVideo(video) {
