Is it possible to hide the file upload date to the site for the user?

Question

System administration

I immediately apologize for the possible mismatch of tags, but I don’t know where to put the question.
In general, there is a site, a file is loaded on it in the admin panel and displayed on the page (a picture, a document is not the point). Each file has a modification date, which can be viewed on the client side by opening the devTools network tab, selecting a file, you can see a line in the last-modified headers.
Is it possible to hide this line for the user (for a scrambled user)? And ideally, the customer wants to change this date, according to the date of publication of the record.

When setting the post publication date, you can change the modification date of related files.
