Need a way to disable Steam Input for added Non-Steam Games

[Flappy Pannus]

There are some games where Steam's xinput emulation causes problems with the gamepad working properly, and as of now if they're non-Steam games you've added, there's no way to disable Steam's controller support per-title, you have to disable it through Steam entirely.

Obviously this is a huge hassle when these games are encountered - please add a way to disable Steam controller support on an individual game-basis for non-Steam games.

This is a old post, but I still wish to share a way to do that.

So I came across this support article for Rocket League (https://support.rocketleague.com/hc/en-us/articles/360022354994-How-do-I-Disable-Steam-Controller-Configuration-in-Rocket-League-)
And noticed Controller Options -> Steam Input Per-Game Setting are available even for non-steam games in Big Picture Mode. Setting it to Forced Off does work as indented.

Why the option is hidden only in Big Picture and completely not accessible in desktop steam is absurd. Guess Valve thinks those who use controller will also use Big Picture?

The Steam client team really need to add the controller related settings for non-steam to desktop client.
