Hi @kofiantwi
The image that you posted shows that ''Kernel DMA protection is on'' and not off, so I'm confused as to what you want to do?
Here's an [https://www.dell.com/support/kbdoc/en-us/000195978/how-to-enable-or-disable-hardware-virtualization-on-dell-systems|article] that shows how to enable/disable this setting in BIOS (if it is available there in your model laptop that is).
