Sorry for the delay.
Thanks for clarifying and further checking this, Dong.
I think some platforms in https://github.com/tianocore/edk2-platforms would do 
this before EndOfDxe. 
Yeah, I agree with Dong. If UefiPayloadPkg doesn't support trusted console and 
may not support it in the future, I also think it's fine to have this change.

console after EndOfDxe


Trusted console is required for TCG Physical Presence and only trusted console 
could be connected before EndOfDxe. Since TCG Physical Presence is not enabled 
yet in the UefiPayloadPkg, I think it is ok to have this change.
