Exclude an OU from Active Scanning

[Sistemas-IT]

Hello;
We need to exclude one OU from active scanning, i'm looking how to do but i only see an option to limit active scanning to certains OUs, we have more than 25 OUs and we only need to exclude one of them, so this way takes too much time, is any way to exclude only one OU?
Thanks.

If you select the top OU, the child OU's will also be scanned.

Ok.
If I select an OU that contains within other OUs, these also were scanned? or else I have to select each and every one of them?
Thanks

No, sorry.
