Do you mean the page title that appears in Google search results, for example? This title can be changed with various SEO plug-ins. For example, YoastSEO or RankMath can do this for you.

Moved to Everything else WordPress, this is not an Request and Feed topic.
How do I remove my website name from the topics I created? (from the The page I need help with: field)
You can’t and more importantly, The “Page I need help with” field is completely unseen by any search engine. You are worried about a problem that does not exist.
That link in that field can only be viewed by a logged into the forums user. The search engine only sees “[log in to see the link]” and not your URL in that link field.
I will rectify – this is seen as a backlink and everyone who searches the domain on any free backlink checker (like Ahrefs – https://postimg.cc/DmgTFN6z) will see the topic. So I would like to remove it.
