I was asked to purchase a laptop with a 17" screen for a customer who owns a restaurant, so I bought an ASUS ROG G750JM. It's a very capable laptop and has nice features and build quality.
However, when it boots up there's a less-than-professional looking "Republic of Gamers" screen that displays while Windows 10 is being loaded.
I thought this branding was in the EFI partition, so I actually nuked the partition and re-built it using a stock Windows 10 Enterprise install USB. But the branding is still there!
Where is this branding stored, and how can I get rid of it? Is it tied to a secure boot key or something else stored in the BIOS?
Edit: Thanks to all who tried to help, it pointed me in the right direction.
To disable the ROG branding on the ASUS G750JM, one must disable secure boot and enable CSM. The fast boot option has no effect on the ROG splash screen while secure boot is enabled, but secure boot is disabled once CSM is enabled (the option disappears altogether).
I will be leaving secure boot on as I think it will be more important to protect against malware than to get rid of the splash screen - if anyone else has an idea as to what to do (flash new UEFI keys, etc.) Please leave a solution below.

This is called the "splash screen" and is typically stored in the boot settings of your BIOS. Nearly every mobo company has this, but ROG boards are the top end of the Asus line and they are targeted at gamers, who use computers more completely than most anyone else does.
To disable it, go into the BIOS settings (Del or F2, usually) and navigate to the boot menu. You should see an option for disabling the splash screen and showing the POST details there. Enabling "Fast Boot" also tends to hide the BIOS splash screen.
UPDATE: This is Asus Specific. Asus has their own utility to manually change the motherboard splash screen to anything you want. It's called MyLogo. It's a free utility on the motherboard DVD. Don't have the DVD? The disc download for this model is here, and what you need is in Drivers and Tools.
If the download doesn't contain the utility because it's a laptop, I'm sure someone at Asus support can get you the file you need. I strongly doubt you're the first ROG customer who didn't want a serious client that still thinks video games are for children to see REPUBLIC OF GAMERS across the boot screen.
5If your ASUS motherboard has "Asus AI Suite 3" listed in the [Driver & Utility]-->[OS]-->[Utilities] section of the ASUS website, you can use the EZ UPDATE feature to change your boot logo.
It wasn't clear to me that first you need to select the BIOS update file, then you get a 'My Logo' choice that lets you specify your logo image.
