How to list BIOS Major/Minor Release Version using PowerCLI?

I'm trying to make sure that I have the correct BIOS versions on a series of HP Proliant servers running ESXi. I would like to use PowerCLI to return the BIOS Major Release and BIOS Minor Release information for each host.

So far, when using PowerCLI to query the BIOS information, I only get the basic version information ("P89"), as shown below (I've obviously omitted the real hostname values):

PS \> Get-View -ViewType HostSystem -Filter @{'Name' = $servername} | select Name,
>> @{N='BIOSversion';E={$_.Hardware.BiosInfo.BiosVersion}}

Name                        BIOSversion
----                        -----------
$servername                 P89

However, if I SSH into that host I can use 'vsish' to identify the BIOS Major Release and BIOS Minor Release information (i.e. v2.76):

root@<servername>: ~# vsish
/> get /hardware/bios/biosInfo
BIOS Information (type 0) {
   BIOS Vendor:HP
   BIOS Version:P89
   BIOS Release Date:10/21/2019
   BIOS Major Release:2
   BIOS Minor Release:76
   Embedded Controller Firmware Major Release:2
   Embedded Controller Firmware Minor Release:73
}

Is there a way to use PowerCLI to return the BIOS Major Release and BIOS Minor Release data, without having to SSH into the host directly?

Thank you in advance!

If the information is available in PowerCLI, it will be located at $_.Hardware.BiosInfo.MajorRelease and $_.Hardware.BiosInfo.MinorRelease. To join the major and minor versions using version syntax, you can do the following with the -join operator:

Get-View -ViewType HostSystem -Filter @{'Name' = $servername} |
    Select Name,@{N='BIOSversion';E={$_.Hardware.BiosInfo.BiosVersion}},
    @{n='BIOSRelease';e={$_.HardWare.BiosInfo.MajorRelease,$_.Hardware.BiosInfo.MinorRelease -join '.'}}
