It didn’t work the first time I tried turning it off in the pkugins menu.
But then I tried it again and saw it was still on, so I turned it off again and restarted.
Now it worked. Thanks.

check the other answers too, it doesn’t fix it for everyone.
I only tested this on the editor from source. You can edit the file:
$PATH_TO_UNREAL_SOURCE%\Engine\Plugins\Runtime\Steam\SteamVR\SteamVR.uplugin
See that the following line is set to false:
“EnabledByDefault” : false,

no need to restart the editor, still can use SteamVR plugin content and no need to have visual studio to build game 
(you need visual studio if you change the default set of plugins)
Note: some of you are failing by doing UE4 > Settings > Start in VR > uncheck.
The actual instruction is to do Steam > SteamVR > Settings > Developer > Start SteamVR > uncheck.

And now Steam seems to have this setting missing. :’(
This is the real workaround solution. Thanks for that!
Just wanted to add I’m experimenting with OpenXR on Unreal Engine with Windows Mixed Reality, and started getting really annoyed about SteamVR opening every time. I had the SteamVR plugin disabled, but the issue was not resolved until I also disabled the Oculus VR plug-in. There’s clearly some legacy dependencies going on there. I now only have Windows Mixed Reality and OpenXR options selected, and SteamVR no longer opens.
This is the only solution that allows me to test my project with and without VR depending on the need.
Disabling other VR systems!! I had only disabled steamVR and it still opened and annoyed me. Turns out I had to disable openXR as well. (I am using oculusVR).
What seems to have worked for me is disabling manually from the “uplugin” file. Go to Epic Games>Engine Version>Engine>Plugins>Runtime>Steam>SteamVR>SteamVR.uplugin and under “EnabledByDefault”, change to false.
For those still having issues, what seems to have worked for me is disabling manually from the “uplugin” file. Go to Epic Games>Engine Version>Engine>Plugins>Runtime>Steam>SteamVR>SteamVR.uplugin and under “EnabledByDefault”, change to false.
This did the trick for me, thanks!
