Всем спасибо.

В итоге сделал такой конфиг

...
	map $request_uri $topdir {
		~(?<captured_topdir>^/[a-zA-Z0-9]+[/]) $captured_topdir;
	}
...

server {
		listen       80;
		server_name  _;

		proxy_set_header Accept-Encoding "gzip,deflate";
		proxy_set_header Connection "upgrade";
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Host $http_host;
		proxy_set_header X-Forwarded-Proto $scheme;

		gzip  off;
		gunzip on;

		location /test/ {
			proxy_pass https://some_service/;

			sub_filter "'/" "'$topdir";
			sub_filter '"/' '"$topdir';
			sub_filter_once off;
		}
...
