steamtinkerlaunch VS ludusavi

I haven't used it myself but steamtinkerlaunch is definitely your best bet. It lets you easily set up Mod Organizer 2 or Vortex directly on your Deck. The quite extensive wiki will provide more information than I possibly could.

For any problems, suggestions and contributions you might have, please use the issue tracker (which was the preferred way already before)

Tinker Launcher is the easiest way to do it. There is also a third party Linux "port" of MO2 you can install. Tinker Launcher is my preferred method. ProtonupQT is not where you get it from. https://github.com/frostworx/steamtinkerlaunch/wiki/Installation

Another app / set of scripts I have found is https://github.com/frostworx/steamtinkerlaunch.

Yes you can use mods/mod managers with Steam Tinker Launcher

The tool that people often recommend is Ludusavi. I don't know how they play with VN's very random location of saves, though, and even then I mostly use it on Linux where it's easy (if fairly space inefficient) to backup an entire wineprefix/steamcompat folder.

you can try to use this https://github.com/mtkennerly/ludusavi

Ludusavi https://github.com/mtkennerly/ludusavi — this looks like a very neat program but it’s designed for native PC games, not emulation, and I’m not sure how well it would work. Anyone use it for emulators?

ludusavi would be something to look into. It can backup saves, which is what you're after. Most of the time it gets the full save location correct, but make sure. As you don't want to waste time "backing up" to realize it only found the games settings.

i know this comes late, but for anyone who hasn't yet heard of it, there's ludusavi

I don't have any definite plans right now, but I would be interested in exploring it. I just opened a ticket to track the idea: https://github.com/mtkennerly/ludusavi/issues/211
