How to set skipReadyCheck to avoid checking document.readyState?

I noticed in RemoteDebugger there is a skipReadyCheck argument which apparently allows you to avoid checking document.readyState when working with mobile Safari and/or webviews. How can I configure Appium with this argument set to true?

My use case is using Appium to automate mobile Safari on iOS, and my app under test nearly always has a readyState of interactive, so the ready check always fails and Appium times out during initialization. Increasing the timeout doesn’t help, because the readyState simply isn’t going to change in a reasonable amount of time. Nevertheless, the app is ready for an automation session shortly after page load, despite the readyState. How can this check be skipped? Thanks.
