Lenovo Thinkpad E480 Windows 11

Hi, 

I checked the lenovo website (https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-e480-type-20kn-20kq/solutions/ht512623-lenovo-devices-supported-for-windows-11) to see if my thinpad E480 could update to windows 11, and it is specified as a supported pc, but when I check on my laptop, it says it can't install Windows 10. I made sure the install of windows 10 was UEFI, secure boot on, tpm 2 on, etc.. I also installed the lenovo apps like system update and updated the bios. (I tried posting this on the lenovo forums but their website is garbage and wouldn't let me make an account)
