No.
To the contrary, we want to know *why* GHES/HEST doesn't get enabled when
booting. See
dba648300e89 ("ACPI / einj: Make error paths more talkative")
for a good example why.
If anything, you should do the total opposite patch and add more
printks to the error paths so that it is obvious why GHES startup fails.
