I am not the owner, nor creator of luxtorpeda or daggerfall-unity. daggerfall-unity package for luxtorpeda was created by d10sfan, just not merged with master branch because of critical daggerfall-unity bug on Linux, a fix for which was committed by ahouts but did not get into a release yet. All software cloned on my repos is being used according to its licenses.
Since the release of The Elder Scrolls II: Daggerfall on Steam as a free game, there has been no way to launch Daggerfall Unity from Steam without obscure file manipulation or any other sorts of dances with drums. Thus I present you a guide for running Daggerfall Unity from Steam as a native game without much hassle by using a Steam Play compatibility tool called Luxtorpeda.
First, download TES II: Daggerfall on Steam and make sure that you have Steam Linux Runtime installed by running
steam steam://install/1070560 command in the terminal.
Next, if you don't have it, install luxtorpeda. I would recommend installing it by using ProtonUp-Qt. You also will need to select luxtorpeda as a compatibility tool specifically for TES II: Daggerfall in the game properties.
Finally, create a file called user-packages.json in ~/.config/luxtorpeda (create the folder if you don't have it) and paste in the following code:
{

}
Now you can run TES II: Daggerfall on Steam and select Daggerfall Unity as a launch option.
You will also be prompted to install Daggerfall patches in a dosbox window, just enter y and press Enter, both two times.
I was literally just looking into how to do this on Ubuntu, and luckily I find this guide that was coincidentally made a couple of days ago. Works great, thanks a lot!
