Windows 10: Does Compatibility Support Module (CSM) hinder Windows 10 performance?

I just found out that my SSD C: drive is in the MBR format before Windows 10 was installed and therefore in the UEFI the CSM (Compatibility Support Module) mode is enabled.

I would like to convert the C: drive to GPT and disable the CSM in UEFI but before going through all the hassles of doing that and risking the pc not booting at all I would like to know if CSM mode has any serious impact on Windows 10 performance once the Windows loaded.

My pc is a Ryzen 2600x and TUF b450 plus gaming motherboard could it be more beneficial to run it entirely in UEFI mode under Windows 10 environment?

(I do not worry much about the boot time advantage of UEFI mode as my pc has tons of USB external hard drives and it took ages to boot up anyway).

If there is no real performance benefit to disable the CSM mode once I am in Windows I will not consider going through the risk of converting MBR to GPT.

Thanks and Regards,

XFX R9 290x Not UEFI?

At my BIOS, there is this:

CSM (Compatibility Support Module)
Allows you to configure the CSM (Compatibility Support Module) items to fully support the
various VGA, bootable devices and add-on devices for better compatibility.

** Launch CSM [Enabled]

[Auto] The system automatically detects the bootable devices and the add-on devices.

[Enabled] For better compatibility, enable the CSM to fully support the non-UEFI
driver add-on devices or the Windows UEFI mode.

[Disabled] Disable the CSM to fully support the non-UEFI driver add-on devices
or the Windows UEFI mode.

So, if I set [Disabled] I got this:
