david3der sure thing, it's not a problem, it's actually good for others visiting the forum to see clear information on how things work. So yes _RNToggleCyclesExport command is a hidden command like a few others, like _RNShowLogs or _RNUnsafeExport, as those are features that are not used daily by most users. Just type in and hit enter. It gives no feedback, but if you open the raytraced viewport RN will no longer export ecosystems and won't clear the display buffer as you requested.
*NOTE: If you use those frequently just create a button and provide the command so you wont need to type it in each time.
