I need Windows Support drivers for iMac 2017

I recently wiped my Windows partition (external drive) due to instability after updates.

I also lost my Windows Support drivers in the process.

Downloads from Bootcamp Assistant 6.1 (Sierra) does not give a full complement. Now my new Windows 10 Home Edition has no WIFI and Sound. Not sure what else is missing.

May I request anyone who has that Windows Support download to send me a copy? Apple Support will not make this available. They require me to upgrade to Catalina and use newest Bootcamp for downloads.

I do not wish to deal with Catalina restrictions on my older softwares. So I am not going to upgrade my OS.

Thanks.
