Can I filter on hostnames in an array?

I'm running the following script, it should display the critical vulnerabilities on MacOS systems.

//List critical vulnerabilities on all MacOS endpoints
config case_sensitive = false
| dataset = va_cves
| filter os_type = ENUM.MACOS and severity = ENUM.CRITICAL
| fields severity,name,description,affected_products,type,severity_score,os_type,affected_hosts_count,affected_hosts,modification_date,publication_date,exploitability_score
| sort desc severity_score

The problem is that the affected_hosts array also contains Windows systems that are affected by the same CVE's.
How can I filter so it only reports MacOS systems?
All our Macbook names start with "MBP-" but I was not able to filter on that , so far.
