Feed in your model number and check the documentation for your hardware.
Check the section in the manual
Use VPN to Access Your Network
You may have done that already. I can't tell from your message.
I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.
While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

There are always two parts to VPN:
A VPN Server which accepts connects from one or more
VPN Clients and creates an encrypted "tunnel" between each Client and the Server.
Any number of client devices (computers, smartphone, tablets, etc.) on the Orbi LAN can load any VPN Client they want and connect to the VPN Server which supports that client. (i.e. NordVPN, ExpressVPN.... there are dozens of VPN servers.
Netgear routers support one VPN Server package: OpenVPN. See page 121 of the User Manual:
This allows remote OpenVPN clients (in a coffee shop, at a friend's house, at a hotel, etc.) to open an encrypted connection from that location to the Orbi LAN in order to access devices on the LAN (including the router itself). One creative person posted about using the VPN capability to make it appear that he was at home in order to access video streaming that was blocked at his physical location. (probably a "sin" of one sort or another)
So, if the goal is to have home devices bundle all their connections to the internet through a VPN, the answer is "no". Not with Express VPN. Not with OpenVPN. Just "no".
(You probably already discovered this information already, but once I get typing there is no going back.)
