Would be cool if implemented.
Here is a ready to go code that i use for myself. Should be able to be used on all Nvidia GPU's.
Copy and paste in PowerShell if you want to give it a whirl.

Code:

$gpuInfo = Get-PnpDevice -Class Display | Where-Object { $_.FriendlyName -like "*NVIDIA*" } | Select-Object -First 1
if (-not $gpuInfo) {

Read-Host -Prompt "Press Enter to exit"
exit 1
}
$gpuName = $gpuInfo.FriendlyName

if (-not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
Write-Host "Please run this script as Administrator."
Read-Host -Prompt "Press Enter to exit"
exit 1
}
# Get GPU class GUID
$classGuid = $gpuInfo.ClassGuid.Trim('{}')

$classGuid | Set-Clipboard

} catch {

}
}
if (-not $matchingPath) {
Write-Host "No matching DriverDesc found for '$gpuName'."
Read-Host -Prompt "Press Enter to exit"
exit 1
}
Write-Host "Found matching registry key: $matchingPath"
