For full list of options: https://docs.python.org/3.9/using/windows.html

/quiet = To completely hide the installer UI and install Python silently, pass the /quiet option.

/passive = To skip past the user interaction but still display progress and errors, pass the /passive option.

/uninstall = The /uninstall option may be passed to immediately begin removing Python - no prompt will be displayed.

All other options are passed as name=value, where the value is usually 0 to disable a feature, 1 to enable a feature, or a path. The full list of available options is shown below."

* InstallAllUsers - Perform a system-wide installation. (default 0)
* PrependPath - Add install and Scripts directories to PATH and .PY to PATHEXT (default 0)
* Include_test - Install standard library test suite (default 1)
* ...

For example, to silently install a default, system-wide Python installation, you could use the following command (from an elevated command prompt):
python-3.9.1-amd64.exe /quiet InstallAllUsers=1 PrependPath=1 Include_test=0

This will install to:
C:\Program Files\Python39\python.exe

python-3.9.1-amd64.exe /quiet InstallAllUsers=1 PrependPath=1 Include_test=0 TargetDir=C:\Python39

Make python3.exe work:
copy C:\Python39\python.exe C:\Python39\python3.exe

Delete this:
%USERPROFILE%\AppData\Local\Microsoft\WindowsApps\python3.exe

del "C:\Users\user\AppData\Local\Microsoft\WindowsApps\python3.exe"
