how turn off safari experimental features from WKWebView

I am using WKWebView to run a react app inside my IOS app. I managed to turn off the experimental feature (NSURL Session WebSocket) of safari on the device's settings. But how do I do the same on code for WKWebView?

@andrewleong We have also seen issues with this setting, did you find a way for disabling it? is it even possible?
