There could be many possibilities:
- You can use computer name relevance to filter out device which you want to exclude, example:
name of computer != "YourDeviceName"
OR
(it as string as lowercase does not contain "YourDeviceCommonThing" as lowercase) of name of computer
- if its one time requirement & you want to exclude few machines, example:
(computer name as uppercase) is not contained by set of (("Server1";"Server2";"Server3") as uppercase)
- If its a frequent requirement, you can create a computer group & exclude whole group from it, example:
- You may also try client-setting based exclusion based on a fixlet or the entire site.
