Enable Split Tunnel in your Norton product to manage your VPN traffic
The Split Tunnel feature in the Norton app lets you exclude some of your apps from the VPN channel while other apps access the Internet directly.
You could try the split tunnel feature of the VPN. See this Norton blog article for help setting this up. https://community.norton.com/en/blogs/product-service-announcements/enable-split-tunnel-norton-secure-vpn
Just be sure you are adding the .exe file for your game to the split tunnel apps.
