With the help from reddit, it works now! The reason is I need to remove the
code added by this patch.
https://review.coreboot.org/c/coreboot/+/38723/6/src/mainboard/lenovo/t440p/romstage.c
This patch is for dGPU, my model does not have dGPU. I didn't thought it would
affect my model, but
I have almost tried everything these days trying to boot Windows 10 using T440p
with coreboot, but still haven't succeed.
I had created my Windows 10 installer usb by writing the
en_windows_10_business_editions_version_1909_updated_jan_2020_x64_dvd_e9cb5542.iso
to usb drive through Rufus, and

Yes it added. I see the option is on by default for both T420 and T440p.

I'm trying to debug T440p's display problem, tested many times and also
compared it with T420. Here are the results:
1, Run VGA Option ROMs+Legacy VGA text mode+VGA BIOS+SeaBIOS:
T420: Everything works fine
Can see SeaBIOS menu?: y
Can see Linux/Windows bootloader? (the Manjaro's start screen
does boot the archlinux in UEFI mode. I'm wondering is this the problem with
my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with
tianocore) or the tianocore has nothing to display to select boot media?

I have just corebooted T440p. Then I noticed some graphic display problems...
Firstly I "Use libgfxinit" with "Legacy VGA text mode", insert a usb disk with
archlinux's latest install image iso. I can see a text mode of archlinux's
start screen.

I'm trying to build coreboot for T440p and still can't boot. I have tried the
official repo's latest master branch, it can't boot. The power button led is
on, keyboard led on for a second and then off, fan is on, but the screen is
not. I don't have a debug device. Ordered a FT232H but it's on
