Hello!
I have the same issue on my Dell G3 15 laptop (Windows 11): I did update BIOS (current version: Dell Inc. 1.20.0, 2022-12-22) and also removed a problematic driver that is now no longer listed (Published name "oem14.inf"). I still cannot turn the Memory Integrity on, despite having no other drivers listed as problematic.
I wanted to send two printscreens so you could have a look yourself, but it seems that I cannot attach any images. Do I need a specific format (I tried JPEG and PNG) or is it because I am not the original person to ask the question?
Thanks in advance for your help!
