Change default printer on Windows 11 [delphi] [windows-11] [printing]

and it gives a solution when Printer preferences ‘Let Windows manage my default printer‘ is off.
There’s a way, in Delphi 11 or 12, to get and change the Printer preferences ‘Let Windows manage my default printer‘ to off when it’s on ??

Thanks to all for any help.
