So a picture would be helpful. The only thing I know of is that on older xct they didnt have lockouts but had a preload adjuster like they do on the left side of the fork. the newer forks have a lockout that rotates around to lockout the fork from moving at all. So it depends on what you mean. a picture would help us identify what you mean by lockout lever. if its just the preload dial its not convertible. you only have two more posts before you can post links and pictures. find some other posts around try to get that count up and come back with some pictures.
