Can we set the URL of the portal created by the UI Builder to a URI like /csm in ServicePortal?

Dear community members

I am currently working on customizing our ServicePortal using the UI Builder.

The current URI is https://FQDN/x/xxxxx/"mysettingname".

Is it possible to set the URI of the portal to a specific URI (https://FQDN/"mysettingname") such as /csm?

If so, could you please guide me through the steps to achieve this? Your assistance would be highly appreciated.

Thank you and looking forward to your response.
