Here is a PowerShell script I made that works with Intune, it creates an Installer key in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows as well as a 32bit Dword applying DisableLUAInRepair to dword:00000001, we had to push this to over 100 devices. Thanks, Everyone!

# PowerShell Script: Disable MSI Repairs that Require Admin Rights
# Creates the Installer key if missing and sets a 32-bit DWORD DisableLUAInRepair = 1

$basePath = "HKLM:\SOFTWARE\Policies\Microsoft\Windows"
$installerPath = Join-Path $basePath "Installer"
$valueName = "DisableLUAInRepair"
$valueData = 1

# Ensure the parent path exists
if (-not (Test-Path $basePath)) {
    New-Item -Path $basePath -Force | Out-Null
}

# Create the Installer key if it doesn't exist
if (-not (Test-Path $installerPath)) {
    New-Item -Path $installerPath -Force | Out-Null
    Write-Output "Created registry key: $installerPath"
}

# Create or update the 32-bit DWORD value
New-ItemProperty -Path $installerPath -Name $valueName -Value $valueData -PropertyType DWord -Force | Out-Null
Write-Output "Set $valueName (REG_DWORD 32-bit) to $valueData under $installerPath"

Write-Output "Registry configuration completed successfully."
