How to have standalone build use discrete GPU by default?

I discovered that Windows laptops will run my standalone build (made in 5.6) with integrated graphics by default. The user can force the game to use the discrete GPU in the OS, e.g. through an Nvidia profile, but I would like to have this happen automatically.

I can't find any mention of this in the documentation, aside from some MacOS command line flags for the player. I've seen other Unity games that work as expected and use the performance GPU by default.

Any leads on how to select the best GPU for the user (programatically or by command line)?

Thanks!
