How can I install git (with bash on PowerShell) on PowerShell? - The first knowledge sharing application in Vietnam

https://gitforwindows.org/ has an option to put bash into PowerShell. I need that so no installing WSL and etc. I need to install git unattended, that is, with command line only. Existing tutorials like this only launch the installer using PowerShell, but I have to use the mouse to install stuff.

So, how can I install git, with bash on PowerShell, using PowerShell?

UPDATE:

I tried

Write-Host "Installing Git for windows..." -ForegroundColor Cyan
$exePath = "$env:TEMP\git.msi"

Write-Host "Downloading..."
(New-Object Net.WebClient).DownloadFile('https://github.com/git-for-windows/git/releases/download/v2.37.1.windows.1/Git-2.37.1-64-bit.exe', $exePath)

Write-Host "Installing..."
Start-Process msiexec.exe -Wait -ArgumentList '$exePath /NORESTART /NOCANCEL /SP- /CLOSEAPPLICATIONS /RESTARTAPPLICATIONS /COMPONENTS="icons,ext\reg\shellhere,assoc,assoc_sh" /LOG="C:git-for-windows.log"'

git --version
bash

but it gets stuck on “Installing…” and does not print any other outputs.
