Facetime Camera on Windows

Hello, I am using this device:

Apple iMac 27-Inch "Core i7" 3.8 (5K, 2020)

Can be identified by: Retina 5K, 27-Inch, 2020 - MXWV2LL/A - iMac20,1 - A2115 - 3442

I ran into strange problem, after downloading Windows Support Software in macOS through Bootcamp, installing Windows side by side macOS using same Bootcamp Utility I have noticed that in Windows 10 (20H2 Build) Facetime Camera device is using generic Windows USB camera driver instead of one provided in Support Software. I cannot install that driver because Device manager says that is not compatible with camera device (I try to Update driver through Device manager) or just regularly installing - nothing changes in device manager or whole system.

I have looked up driver provided in Support Software by Apple and found that they are completely different:

Why I am trying to use Apple Driver? Because I have this issue:

FaceTime Camera doesn't work properly/reliably in Windows. Sometimes it works in desktop Apps like Teams, Scopia Client, Skype and etc., and sometimes it just shows blank, black view, camera light is on (green). I must say that I have 10 of those computers all acting same, in fresh Win10 installs, with Bootcamp software, so it's not single Mac computer camera device problem. Please help, we have to use Windows OS on those computers and we have way more incoming of them. All solutions I have tried so far - failed to make camera's reliable.

Things I have tried so far:

1. ManyCams virtual camera software
2. Changing apple driver hardware id to match device id provided in Device manager and install Unsigned driver provided by Apple and modified by me, Windows OS crashes

All Windows Camera privacy settings are Off and all rights to access camera is ON.
