On AirPrime EM7565 product page, I found driver package for Windows 7/ Windows 8 /Windows 10 Driver Package.
I didn’t find driver package for Windows server 2019 => does EM7565 card not support Windows server 2019?
Windows 10 driver package should work for Windows 10 Server 2019 but you should use the latest driver package that has RS5 signature as Windows Server 2019 is based on the Windows version 1809 codebase.
The driver packages posted on the Source are QMI based that mostly targeted for M2M customers. Please contact your distributor for appropriate driver package if you intend to use the WWAN module on Windows Servers.
