install safari on W11 PC?

No. There is no version of Safari for Windows.

You can use the built-in Edge browser, or a third party one like Firefox, Opera, or even Chrome amongst many others.

The last Safari for Windows release was discontinued about a decade and a half ago.

Apple hasn't offered a Windows version of Safari for a very long time. What you may be able to find to download will be grossly outdated.
