Can i define in netbird a client/peer to act as an relay

Hello!
Is it possible to define in netbird similiar to tailscale that a a netbird peer(client) acts also as a relay? and if yes how.
I am using netbird cloud with Nginx Proxy Server and ADguard as DNS Server and it seems my LTE router is CGNATed :/.

Thank you

What does a relay do in Tailscale exactly? Refer all data from inside of the network to any VPN client that has access to it?

well the relay routes the traffic from my knowledge and as I am behind a cgnat router in case I am within the VPN all the traffic is routed via the netbird relay in Germany for example which slows down the connections massively.
So is it possible to use a netbird client as the relay?
