Yes. Install IIS with the URL Rewrite Role Service on the same box as UrBackup. You will also need to install application request routing: Application Request Routing : The Official Microsoft IIS Site.
Configure your website bindings in IIS to listen on 443 and the appropriate corresponding certificate.
Then create a Reverse proxy URL rewrite rule and make it like this:
The “Rewrite URL” should be that of urbackup web interface
Lastly create a firewall rule that restricts access to TCP55414 to only allow in traffic from the local IP address of the UrBackup server. This means that the local IIS webserver can forward traffic to it, but no other device can reach that port.
