How Switch from IL2CPP to .NET ?

Hello i have a question, i’m building an app for Hololens2 in order to use UWP library in my code i need to switch my Scpriting Bakcend from IL2CPP to “.NET” i’m getting in to Project Settings > Player Other Setting> Scrpting Backend but it’s grayed and i can’t switch. Is there a way to change this ?

IL2CPP is the only scripting backend option available for UWP.

Can I ask why you are looking to switch? Is there some issue that we can address?
