Question Continue using UEFI and Legacy OPROM, or just switch to UEFI in the BIOS ?

[Blackapino]

OS: Windows 11

I'm Wondering if I should continue to use UEFI and Legacy OPROM for My Boot Device Control or should I just switch to UEFI ?

I have UEFI only selected for Boot From Storage Devices and the Boot from PCI-E/PCI Expansion Devices is just set to Legacy Only.

We're going to need some context, what is the make and model of your motherboard? Please don't say to look at your sig space specs since that will change over time and this thread will be rendered moot to the end user in the same boat as you're in now.

If you installed the OS while in CSM mode, then you will need to reinstall the OS once you've disabled it in BIOS. That being said, I make sure that everything is set to UEFI unless I'm having compatibility issues with a device/component I've migrated from a very old system.

Those probably are default settings.
Why do you want to change them?
Is something not working?

If I wanted to Run Memtest86 it says it's only supported by UEFI

That means, you have to boot from memtest86 media in UEFI mode.
Boot from:
[UEFI] USB flash drive
boot entry and NOT
USB flash drive
boot entry.
