iPad pro portrait mode

[Blancey Gibson]

Anyone know anyway to get apps to play in portrait mode?
I'm doing a custom dash in my truck and using the iPad as my screen, that being said the iPad will be mounted Vertical and will not be able to turn to allow landscape mode, I want to be able to use a few apps that only work in landscape and was wondering if there is any way to have it play in portrait mode?
Thanks for reading and replaying
