How to use BootSectorScan with MpCmdRun (Windows)

The MpCmdRun documentation, such as it is, shows the existence of a "-BootSectorScan" option which "enables boot sector scanning" and that is "only valid for custom scan[s]". However, I cannot find a way to actually use it or, perhaps, find any indication that it has any effect.

I've tried the following:

[1] MpCmdRun -Scan -ScanType 3 -BootSectorScan
[2] MpCmdRun -Scan -ScanType 1 -BootSectorScan
[3] MpCmdRun -Scan -ScanType 2 -File C:\Temp -BootSectorScan

[1] fails with an "invalid argument" error. [2] and [3] run, but I cannot find any indication (in MpCmdRun.log or in event viewer) that any boot sector scanning was done.

What is the proper way, if any, of using the -BootSectorScan option, and how do I tell that it actually did anything?

I cannot find a way to actually use it

MpCmdRun -Scan -ScanType -BootSectorScan

So omit the -ScanType argument
