Caveat: Given that your code makes ongoing requests in a tight loop, it should only be run against a test web service / site.

I don't want to use do or try or catch methods.

In Windows PowerShell, you must use try / catch:

while (
 429 -ne 
 $(try { $null=Invoke-WebRequest @req } catch { $_.Exception.Response.StatusCode })
) { }

In PowerShell (Core) 7+, you can use the -SkipHttpErrorCheck switch:

while (429 -ne (Invoke-WebRequest -SkipHttpErrorCheck @req).StatusCode) { }

See this answer for details.
