How to change default boot option for OpenCore

It used to choose the last volume when I boot up into open core, allowing me to ignore the prompts and let OS Catalina boot as normally. For some reason recently, It has been locked to the first EFI partition (Which Is actually a separate drive carrying a separate test version of MacOS).

I would like to change the default boot option, and I assume it would be in the config.plist, however cannot find anything related. TIA
