     .SYNOPSIS
     Dynamically determines the desired operating system disk based on a calculated MediaType and BusType priority.

     .PARAMETER BusTypeExclusionExpression
     A valid regular expression to exclude disks for from consideration based on their bus type. By default, USB based disks will be excluded.
 
+    .PARAMETER DiskSizeThresholdInGB
+    Grants the ability to filter out disks that are smaller than the specified value in gigabytes. This is useful for situations where an Intel Optane Memory Cache might be present.
+
     .NOTES
     By default, the operating system will get deployed onto the fatest and smallest disk.
