networking – Setting up company VPN only for RDP, not for internet

I’m setting up VPN for my organization on Windows Server 2019. All works well but the vpn clients navigate on internet with VPN server IP. So I disabled the NAT on windows server and the clients can’t navigate on internet.
They have to disable “use default gateway on remote network” option in vpn connection to use their connection.

How can achieve the same result of disabling “use default gateway on remote network” without disable this option? Is it possibile to setting up the VPN SERVER only for LAN to login in rdp session?

Thanks
