ROTR won't disable, ROTR won't disable and I don't want to uninstall Options

[Frongus]

Hi, I used to be able to disable the mod by just pressing 'quit' on the launcher but ever since EA switched Origin for the EA App, it won't work anymore.
Anyone know a fast way to fix this or to disable the mod that doesn't involve having to uninstall?

(sidenote: I also wanna try 1.87, but it keeps telling me an error occured whenever I try to boot it up, even if I run it with administrator.)
