From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Did you look into network namespaces? With these you should be able to dedicate a namespace for the VPN adapter and then move discord into it, at least with wireguard it works flawlessly.
Do you have any tool to help with that? Ive set this up in the past, but it was pretty hands-on namespacing to get it to work rootless.
Edit: For completeness, here is a script similar to what I use.
I am not sure if this is helpful but I just created a systemd unit that sets up the network namespace in the background. Then, as I use nixos, I add the wireguard VPN to nix and with
networking.wireguard.interface.name.interfaceNamespaceyou can then move it into the container. For running applications I cannot really comment because I have only one service making use of the VPN which runs inside a NixOS container for which the namespace can be configured with--network-namespace-path=/run/netns/…
