Switch OCIO on the fly

Hi, I was wondering if somebody manged to switch the OCIO on the fly. For example I’m using ACES.ocio and want to switch to another OCIO file without restarting RV. I manage to repopulate the menu with the new OCIO transforms but it seems like in the background the old one is still loaded. Is there a way to “unload” the ocio and “restart” the source setup?
