Hi @Jason Steeves ,
You can more or less import any management pack, but remember that not all versions are officially supported in newer SCOM versions.
For the supported UNIX and Linux operating system versions see:
Supported UNIX and Linux operating system versions
https://learn.microsoft.com/en-us/system-center/scom/plan-supported-crossplat-os?view=sc-om-2019
This doesn't necessarily mean that the management packs won't work, you'll have to use them at own risk, most likely they would work but it has not been tested officially by Microsoft.
