I already have Windows 11/10 installed. The built-in Windows 11/10 Disk Management tool won't allow me to operate on the EFI partition because the extend volume option is grayed out."

If you have a basic understanding of BIOS and UEFI (EFI), you'll surely know how to check, find and determine whether you are using it or not.
Method 1. As a practical matter, EFI partitions are found on GPT formatted drives and are used to boot the operating system. Although the UEFI spec and the GPT partitioning scheme are independent of one another, Windows requires that you use them together. You cannot boot Windows from an MBR formatted disk on a UEFI system, and you cannot boot from a GPT disk on a legacy BIOS system. That's how you should know how your system is configured.
Method 2. Go and check in the system information window. Type MSInfo32in the Run box and open the window. Find the "BIOS Mode". If your PC uses BIOS, it will display Legacy. If it is using UEFI so it will display UEFI.
