We just started using the Latitude 5320 after 5310 was discontinued. We use MDT to create and deploy images. We set the storage in BIOS to AHCI, and Secure Boot off. This is standard practice. What we can not disable all the time is HTTPSBOOT, which is something new I have not seen previously. I built the image from scratch using the Windows 10 media creation tool and 20H2 build. After I installed the OEM version, installed all drivers, I captured using MDT and deployed the image. Everything was working fine for a day, but then randomly when shutting the lid , which I have set to sleep on battery, and waiting about 10 minutes, we open the lid and when it would normally come back up to Windows, we get the attached error. After that, going into BIOS doesn't show the M.2 at all until a couple more reboots. This doesn't happen every time but is happening. 

 

Error:

"HTTPSBOOT Failed to initialize network connection"

 

Didn't know if anyone else has ran into similar situation and had a fix or not. I do not believe this to be a driver issue since we are not using RAID in the BIOS and because this typically happens after coming out of sleep or when first trying to boot the device up. And then when the BIOS no longer shows an M.2 drive at all.

Thanks in advance for any assistance.
