Help with BIOS settings

[Aqualung]

Guys, there's a bunch of BIOS settings that I need help with. I tried AI, but it didn't help much. I am a Linux user, and I have been struggling to get my Thunderbolt eGPU work. Ideally, I would also like some sort of an explanation for each of these settings:

1. Should I enable "ACPI Auto Configuration"? Default is disabled.
   
2. My laptop stays mostly docked: should I enable "IUER Dock"? (Disabled by default.)
   
3. Should I enable "VTIO support"? (Disabled by default.)
   

Laptop is an LG Gram 2023, with a Phoenix BIOS. As you guys can imagine, LG support is useless in such matters. A further annoying issue is that the settings revert to the default values after a hard reboot: how can I prevent that from happening? I tried disabling the "self-healing" (or whatever it's called) feature, but that seems to be reverting to "Enabled" by itself, and not just when doing a hard reboot, but upon normal(!) reboots as well.
