Yeah. It can be done using ExecuteScript. You can use Groovy and execute as simple as the following line to run a shell command.

"dmidecode".execute()

or to read the result generated:

def result = "dmidecode".execute().text

Then when you're done reading the required value/data from the result, you can use something like the following to assign the value as a FlowFile attribute

flowFile = session.get()
if(!flowFile) return
def dmidecodeUuid = ... // your logic to read the UUID from dmidecode
flowFile = session.putAttribute(flowFile, 'dmidecode.uuid', dmidecodeUuid)
session.transfer(flowFile, REL_SUCCESS)

That's just a rough code which was quickly made. More details on ExecuteScript can be found at:
