Using PC with VPN client behind VPN router

I have an ASUS AX5400 router with NordVPN active which I use at my home office by default to connect any company (Windows) devices.

Questions:

  • Will a VPN client (to access the company intranet) create a VPN within the VPN or is it somehow bypassed?
  • Is it possible for the admin to detect that I am e.g. at my beach house in the carribean or at my home office in Gotham City?

If so

  • What is the best approach to prevent that?

I have admin rights on all devices. Nonetheless, group policies, client settings are set by admin.
