Make Linux File System Case Insensitive

I deployed a website on Linux using NGINX as there server.

My files are in lower-case and are located at /susr/share/nginx/html When I request for the files using upper-case it returns a 404.

Example: https://example.com/about works fine but https://example.com/About return a 404 error.

server {
         listen 80;
        listen [::]:80;
        
        server_name example.com www.example.com;
        root /usr/share/nginx/html;

        location ~* ^/ {
            index  index.html index.htm;
            # Remove .html extension
            if ($request_uri ~ ^/(.*)\.html(\?|$)) {
                return 302 /$1$is_args$args;
            }
            try_files $uri $uri.html $uri/ = 404;
        }
        # remove trailing slash
        if (!-d $request_filename) {
            rewrite ^/(.*)/$ /$1 permanent;
        }
        
        error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;

        location = /50x.html {
            root   /usr/share/nginx/html;
        }
            
        
    }

My research shows that the problem is not the nginx configuration but the Linux file system.

How can I enable case-insensitive on Linux to make the nginx to treat lower and upper case files and directory as the same.

Thank you.
