How to set Microsoft Edge startup page(s) on many PCs in batches?

I know that the setting of startup page(s) of Microsoft Edge is stored in the registry keys located below:

"HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\Protected - It is a violation of Windows Policy to modify. See aka.ms/browserpolicy"

There is a Reg_Binary value ProtectedHomepages is just stored the setting of the startup page(s) , anywaycannot be edited directly.
But if I export the .reg file from one PC, it only works on this PC, yet will not work on any other PCs.

Sigh...

As my saying of the third reply on my thread Edge vs. IE, why do I prefer IE?

I can set the IE's start page by a batch file that its contents are as below:
SetIEStartPage.bat
reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main" /f /v "Start Page" /t REG_SZ /d "https://www.microsoft.com"
Yeah, to IE, I can do this by a batch file;
but anyway I can't do such to Edge!

Please teach me - how to set the Microsoft Edge startup page(s) on many PCs by a batch file or any approaches in batches (just like in IE)?
