This can be done quite easily.

You can look at this component’s code and adapt it to hide elements with CSS (target .similar-topics) in users’ preferences settings. That’s exactly what I’ve done on https://unicyclist.com/, where users have a setting to hide the donation icon in the top right of the header.

Basically, the only change I made to the original plugin is that I store the setting in a cookie (I want to remind my user to donate each year for the servers’ fees).

Here’s my own theme component code:

<script type="text/discourse-plugin" version="0.8">
    // set the cookie duration to 1 year
    function setHideDonationCookie(value=null) {
        var now = new Date();
        var time = now.getTime();
        var expireTime = time + 1000*60*60*24*365;
        now.setTime(expireTime);
        document.cookie = 'donationButton=' + value + ';expires='+now.toUTCString()+';path=/';
    }
    // return the cookie value
    function getCookie(name) {
        var dc = document.cookie;
        var prefix = name + "=";
        var begin = dc.indexOf("; " + prefix);
        if (begin == -1) {
            begin = dc.indexOf(prefix);
            if (begin != 0) return null;
        }
        else
        {
            begin += 2;
            var end = document.cookie.indexOf(";", begin);
            if (end == -1) {
            end = dc.length;
            }
        }
        return decodeURI(dc.substring(begin + prefix.length, end));
    } 

function getToggleDonationIcon() {
  let pref = getCookie('donationButton');

  let result = settings.default_enabled;
  if (pref !== null) {
    result = pref === "true";
  }
  return result;
}

// We add the CSS rule in the HTML code
if (getToggleDonationIcon()) {
  let style = document.createElement('style');
  style.innerHTML = ".header-icon-help-fund-servers-fees{ display: none; }";
  document.head.appendChild(style);
}

// technically we only want to amend current user here
api.modifyClass("model:user", {
  toggleDonationIcon: function() {
    return getToggleDonationIcon();
  }.property()
});

api.modifyClass("controller:preferences/interface", {
  actions: {
    save() {
      this._super();
      // set the cookie value as the setting value
      if(this.get("model.toggleDonationIcon") != getToggleDonationIcon()) {
        setHideDonationCookie(this.get("model.toggleDonationIcon").toString());
        if(this.get("model.toggleDonationIcon") == false) {
            document.getElementsByClassName("header-icon-help-fund-servers-fees")[0].style.display = "";
        }
        else {
            document.getElementsByClassName("header-icon-help-fund-servers-fees")[0].style.display = "none";
        }
      }
    }
  }
});
</script>

<script type='text/x-handlebars' data-template-name='/connectors/user-preferences-interface/add-selector'>
  {{preference-checkbox labelKey=(theme-prefix 'donation_icon_toggle') checked=model.toggleDonationIcon}} 
</script>
