Most motherboards will work with only few changes from Optimized Defaults.

Here's a Recommended BIOS/UEFI Settings for Optimal performance. The settings are valid for Intel and AMD PCs and Laptops

To access your BIOS/UEFI, press and hold Delete key on your Keyboard. The key maybe different in your case. Refer to your Motherboard Guide/Manual.

Notes:
  • If you're using IGPU as a Graphics Device, set Internal Graphics to Enabled and DVMT to 64MB.
  • I you're using only Discrete Graphics, set Internal Graphics to Disabled.
  • For some systems, when disabling Secure Boot, you might need to clear the Security keys, Platform Keys (PK).
  • For some laptops, you need to set Administrator password when disabling Secure Boot otherwise you might get "Secure Boot Fail" message when booting using USB installer.
  • For some Dell Laptops, if your Laptop restarts while plugging/unplugging the AC Adapter, try changing the Legacy Option ROMs setting. If it's enabled, try to disable it. If it's disabled, try to enable it.
  • If your Motherboard or the Laptop doesn't have the options mentioned above, you can simply skip those settings.
The more settings about Thunderbolt are explained in the thread below.

You should use UEFI boot mode. As always, UEFI is more better.
