Out of curiosity, why do you want to hide them from yourself?
Honestly? I just don’t like seeing them. If I go to my blog…I just want to see my blog too 
I found a solution. This obviously isn’t a scalable solution, and may even not be technically optimal (not sure how this would be handled on larger sites with lots of page loads, etc.), but It is one that works for me since I just have one category for my blog:
ChatGPT gave me this and it worked first try. Just targeting this very specific topic ID and hiding it:
<script>
document.addEventListener("DOMContentLoaded", function() {
var element = document.querySelector('[data-topic-id="10"]'); //replace 10 with your topic ID
if (element) {
element.style.display = 'none';
}
});
</script>
Viola!
