Can i remove the ocm directories with rm -rf ocm?

Hi experts.I have the following directories, and will like to remove with rm -rf the ocm directories.
We currently don't have the Ocm implanted in our company, and it will not be implanted in the near future.
Can I just do a rm -rf ocm?

/oracle> ls -l|grep ^d
