Disabling Foveated rendering - UE5.4.2 - Standalone Game Project

Hi All, 

Title explains what I'm trying to do - I understand that FFR is a vital part of the optimization process for standalone games however the amount of pixelation that occurs around the users view is too much and causes issues for some users. 

Is there any way to disable FFR or reduce its intensity. I've tried adjusting the FR Level to None in the MetaXR plugin in UE, unfortunately this has not worked and the pixelation caused by the FFR is still present.
